Stem Cell Therapy for Spinal Cord Injury: An Overview
Stem cells proliferate, migrate, and differentiate to form organisms during embryogenesis. During adulthood, stem cells are present within tissues/organs including the central nervous system (CNS) (1–5), where they may differentiate into neurons (6). Since the identification and characterization of stem cells, a great deal of interest has been given to their potential for treatment of spinal cord injury (SCI), traumatic brain injury, and degenerative brain diseases (7–12). Considering their characteristic abilities to self-renew and differentiate into any cell type in the body, the therapeutic promise of stem cells is justified.
Definition and background
After SCI, endogenous regenerative events occur, indicating that the spinal cord attempts to repair itself. Schwann cells, the myelinating and regeneration-promoting cell in the peripheral nervous system, migrate from spinal roots into the damaged tissue and myelinate spinal cord axons (30,31). The expression of regeneration-associated genes is increased in damaged neurons (32,33). There is a surge in proliferation of local adult stem cells and progenitor cells (34–36). However, axonal growth is thwarted by growth inhibitors present on oligodendrocyte myelin debris and on cells that form scar tissue (37–39). Also, the newborn stem cells and progenitor cells do not integrate functionally into the injured spinal cord tissue. Thus, the endogenous regenerative events that occur after injury fail to repair the spinal cord.
Rationale for using stem cells
Improved functional outcome after SCI may be elicited by neuroprotective approaches that limit secondary tissue loss and thus the loss of function. Alternatively, functional recovery could be elicited by axon growth-promoting approaches that result in restoration of damaged and/or formation of new axon circuits that could become involved in function. There is little doubt that stem cells and neural progenitor cells could become invaluable components of repair strategies for the spinal cord. They can become neural cells that may support anatomical/functional recovery. Alternatively, they may secrete growth factors that could support neuroprotection and/or axon regeneration (Figure 3).
Several concepts of promoting physiological recovery in SCI using cellular transplant techniques exist, and include:
Transplanting cells to "bridge" axons in the damaged region, to act as a scaffolding for regrowing nerve fibers to rejoin, via the secretion of growth and neurotropic factors.
Inducing stem cells to form oligodendrocyte precursors to remyelinate damaged axons.
Removing or inactivating growth inhibitory factors and cells such as self-destructive immune cells.
Promoting neorevascularization to support axon regrowth.
Potential benefits and limitations
Stem cell therapy is a promising treatment for SCI due to its multiple targets and reactivity benefits. Cell therapies exhibit neuroprotective and nerve regeneration potential in SCI with different targets and responses to stimuli, such as regulating inflammatory responses, providing nutritional support, and improving plasticity. With these excessive potential mechanisms, various cells from different tissue sources, including bone marrow mesenchymal stem cells (BM-MSCs), umbilical mesenchymal stem cells (U-MSCs), adipose-derived mesenchymal stem cells (AD- MSCs), neural stem cells (NSCs), neural progenitor cells (NPCs), embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and extracellular vesicles (EVs), were studied.
Stem cells may be classified into two main subtypes: adult or somatic stem cells (ASCs), derived from differentiated adult tissue sources, are thought to support repair and regeneration of specialized adult tissue. Embryonic stem cells (ESCs), derived from the inner cell mass of the early stage blastocyst, can be used to produce large quantities of neuron/glial precursor cells, which cannot be easily obtained from adult stem cells. However, unlike adult stem cell recipients, ESC recipients are genetically nonidentical to donors, and may thus need long-term immunosuppressive therapies, increasing the risk of opportunistic infections.
The clinical potential of the above classes of stem cells, with regard to SCI therapy, will be discussed in the following section.
Mesenchymal stem cells (MSCs) are a type of multipotent adult progenitor cells that can be differentiated into several types of mesodermal tissues including bone, cartilage, muscle, and blood vessels. Bone marrow and umbilical cord blood are the richest sources of MSCs, but other sources include adipose tissue, skeletal muscle, trabecular bone, and deciduous teeth. How can these mesenchyme-derived stem cells aid the regeneration of injured ectodermal neural tissue following SCI? True transdifferentiation of an MSC into a functional neuron would require reversion to pluripotent stage, differentiation to an ectodermal precursor, and subsequently, into a neuron. The mechanism of this type of differentiation is highly controversial. More widely accepted is the theory that MSCs can be induced to secrete neurotrophic factors. These may address the complex secondary processes occurring after SCI, promoting axon growth, angiogenesis, and antiinflammatory actions. Thus, one can see how MSCs may provide a powerful therapeutic option in SCI, through the growth of new axons, reestablishment of blood supply to damaged tracts, and prevention of inflammatory cell activation.
The remarkable clinical potential of ESCs amidst the long-standing ethical concerns regarding their development and utilization, have made ESC therapy one of the most controversial and discussed subjects within the scientific community and beyond. The pluripotency of ESCs have allowed researchers to study their potential as both oligodendrocyte and neuronal cell precursors, and ultimately, their role in remyelination and regeneration of spinal cord tracts after SCI. While research into their differentiation into CNS tissue is still in its infancy, many studies have highlighted their efficacy in vitro and in animal models.
Following the discovery of the unusual neuroregenerative capacity of the olfactory nerve fibers that arise from olfactory neurosensory cells, in 1985, Raisman et al. discovered a unique type of glial cell, the olfactory ensheathing cell (OEC) that contributes significantly to the regenerative capacity of these fibers. OECs surround the unmyelinated olfactory fibers from their origin within the nasal mucosa to their synaptic terminals with olfactory bulb fibers in the anterior cranial fossa. In vitro research has shown that OECs play an important role in guiding olfactory nerve fibers to their appropriate target cells within the olfactory bulb via the secretion of neurotropic factors: Nerve growth factor (NGF), brain- derived neurotrophic factor, and glia cell-line derived neurotrophic factor (GDNF).
Types of Stem Cells for Spinal Cord Repair Embryonic Stem Cells
Embryonic stem cells (ESCs) are pluripotent cells derived from the inner cell mass of blastocyst-stage embryos. They have the remarkable ability to develop into more than 200 different cell types present in the human body. ESCs can be isolated from blastocyst-stage embryos, created using somatic cell nuclear transfer, or through parthenogenetic activation of eggs. These plastic characteristics make ESCs suitable for central nervous system repair strategies, as they can potentially differentiate into oligodendrocyte and neuronal cell precursors, contributing to remyelination and regeneration of spinal cord tracts after spinal cord injury (SCI). However, the transplantation of ESCs carries risks such as uncontrollable cell proliferation leading to teratoma formation, genomic and epigenetic changes that could cause transformation, and immune rejection, necessitating long-term immunosuppressive treatment.
Induced Pluripotent Stem Cells
Induced pluripotent stem cells (iPSCs) are a promising alternative to ESCs, offering a patient-specific and less ethically controversial source of pluripotent cells. iPSCs are generated by reprogramming differentiated adult somatic cells, such as fibroblasts, through the introduction of specific transcription factors, including OCT3/4, SOX2, KLF4, and MYC. This groundbreaking technology, first described by Takahashi and Yamanaka, allows for the creation of pluripotent cells from various cell types, both murine and human. While iPSCs share many similarities with ESCs, their tumorigenesis potential, fate in grafts, and overall efficacy are still being investigated.
Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) are multipotent adult progenitor cells that can differentiate into various mesodermal tissues, including bone, cartilage, muscle, and blood vessels. Bone marrow, adipose tissue, amniotic fluid, umbilical cord, liver, and heart are rich sources of MSCs. The most commonly used types of MSCs in clinical practice are bone marrow mesenchymal stem cells (BM-MSCs), human umbilical cord mesenchymal stem cells (HUC-MSCs), and fat-derived mesenchymal stem cells (AD-MSCs).
While the mechanism of MSC transdifferentiation into functional neurons is highly controversial, a more widely accepted theory suggests that MSCs can be induced to secrete neurotrophic factors. These factors may address the complex secondary processes occurring after SCI, promoting axon growth, angiogenesis, and anti-inflammatory actions. The role of MSCs in SCI can be broadly summarized as suppressing immunity against inflammation, releasing nutritional factors to promote neurological recovery, and stimulating angiogenesis to remodel the blood-spinal cord barrier.
Neural Stem/Progenitor Cells
Neural stem/progenitor cells (NSPCs) are considered a promising therapeutic option for SCI repair due to their restricted differentiation into neural lineages. The most frequently used NSPCs include human fetal brain-derived NSPCs (BNSPCs), spinal cord-derived NSPCs (SCNSPCs), induced pluripotent stem cell-derived NSPCs, and embryonic stem cell (ESC)-derived NSPCs. Studies have demonstrated the potential of SCNSPCs in facilitating electrophysiological and hindlimb functional recovery after transplantation into SCI animal models, suggesting that SCNSPCs may be an appropriate candidate cell type for SCI repair.
In addition to NSPCs derived from various sources, olfactory ensheathing cells (OECs) have also shown promise in promoting axonal regeneration and remyelination after SCI. OECs surround the unmyelinated olfactory fibers and play a crucial role in guiding these fibers to their appropriate target cells within the olfactory bulb through the secretion of neurotrophic factors.
Mechanisms of Stem Cell Action in Spinal Cord Injury Cell replacement and regeneration
Stem cells have the remarkable ability to differentiate into various cell types, making them a promising option for cell replacement strategies in spinal cord injury (SCI) repair. With the appropriate combination of growth factors and induction cocktails, embryonic stem cells (ESCs) can be used to obtain neurons and glial cells [46,47]. ES-derived neurons have been shown to survive and integrate after injection into the injured rat spinal cord. Notably, transplanted mouse ESCs have demonstrated the ability to myelinate axons in the myelin-deficient shiverer rat spinal cord, and when grafted into the injured (normal) rat spinal cord, they have resulted in improved functional recovery. Importantly, ESCs have been found to survive well within the injured spinal cord, suggesting the potential for long-term treatments using this approach.
Human neural progenitor cells, harvested from blastocyst-stage embryos, can be manipulated to generate functional neurons and glia. When these cells were grafted into the injured rat spinal cord, some differentiated into oligodendrocytes, accompanied by improved functional outcomes [62,63].
Mesenchymal stem cells (MSCs) from bone marrow also hold therapeutic promise for SCI [64,65]. Although still debated, these adult stem cells have been shown to differentiate into various cell types, including bone, fat, tendon, cartilage, liver, skeletal muscle [69,70], cardiac muscle [71,72], and even central nervous system cells [68,70,73–77]. This versatility makes mesenchymal bone marrow stromal stem cells an interesting candidate for strategies aimed at repairing the injured spinal cord.
Immunomodulation and anti-inflammatory effects
Stem cells play a crucial role in regulating immune responses and modulating inflammation after SCI. Adult stem cells, such as mesenchymal stem cells (MSCs), are more susceptible to immune rejection compared to embryonic stem cells (ESCs) since they express major histocompatibility complex (MHC)-II and CD86. However, adult stem cells can reprogram the inflammatory environment by releasing multiple anti-inflammatory cytokines. Neural stem cells (NSCs) in the spinal cord have the ability to reprogram immune cells after SCI. They promote macrophage polarization towards a more pro-regenerative phenotype, enhancing the expression of anti-inflammatory factors to improve nerve regeneration. NSCs release multiple factors after an injury, such as TGF-β, prostaglandin E, and nitric oxide, which increase the number of regulatory T cells and enhance the expression of pro-regenerative factors. Additionally, NSCs can directly contact T cells and increase regulatory T cell populations, thereby enhancing the expression of anti-inflammatory factors while limiting the expression of pro-inflammatory factors.
MSCs can also modulate inflammatory responses after SCI. They secrete interleukin 1 receptor antagonist (IL1-RA), which can induce the polarization of macrophages into a pro-regenerative phenotype. Furthermore, MSC-mediated overexpression of IL-6 and hepatocyte growth factor (HGF) can influence monocytes and induce the secretion of high levels of pro-regenerative factors, including IL-10, at the injured site for immunomodulation. Moreover, delivered MSCs into the injured spinal cord have been shown to limit the infiltration of circulating inflammatory subsets of immune cells to the injured site and promote the phenotypical changes of macrophages and microglia into a more anti-inflammatory phenotype. MSCs also restore the broken blood-spinal cord barrier to prevent additional damage, thereby enhancing functional recovery after SCI.
Secretion of neurotrophic factors
Stem cells have the ability to secrete a variety of neurotrophic factors that can promote neuroprotection, axon regeneration, and functional
recovery after SCI. Neural progenitor cells can protect against excitotoxicity [91,92] and secrete molecules that could protect neural cells from other death mechanisms [91,92]. Transplantation of these cells into the injured spinal cord could exert neuroprotective effects. Bone marrow stromal cells have also been shown to elicit neuroprotective effects due to the secretion of growth factors [95–98], as evidenced by tissue sparing when grafted into the injured adult rat spinal cord [93,94].
The ability of neural progenitor cells to secrete a variety of neurotrophic factors indicates that they could promote the growth of damaged axons [91,92]. Adult neural progenitor cells have been found to provide a permissive guiding substrate for corticospinal axon regeneration after SCI. Olfactory ensheathing cells, stem cell-like cells, assist axon regeneration in the injured spinal cord by preventing axons from recognizing growth inhibitory molecules, allowing them to elongate into otherwise inhibitory terrain [100,101].
Mesenchymal stem cells (MSCs) can regulate immune function, produce various neurotrophic factors, and promote neural and vascular regeneration, which is closely related to functional recovery after SCI. MSCs can secrete immunomodulatory and neurotrophic factors, including interleukin-6 (IL-6), nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), and vascular endothelial growth factor (VEGF) [77,78,79,80,81]. These factors contribute to the therapeutic potential of MSCs in SCI repair.
Neural stem cells (NSCs) and neural progenitor cells (NPCs) are pluripotent cells capable of differentiating into specific neuronal or glial cells, enhancing remyelination and providing nutritional support, making them suitable for cell transplantation therapy in SCI [38,91–96]. NPC transplantation has been shown to increase the expression of neurotrophic factors such as NGF, ciliary neurotrophic factor (CNTF), BDNF, insulin-like growth factor-1 (IGF-1), and GDNF, which are beneficial for SCI recovery.
Challenges and Considerations Safety concerns and potential risks
Ensuring the safety and efficacy of stem cell-based therapies is paramount. The risk of tumor formation and the potential for immune rejection must be carefully addressed [133,134]. At Visakha Spinetics, we prioritize patient safety by adhering to stringent protocols and conducting rigorous testing to mitigate these risks.
Despite their potential benefits, mesenchymal stem cell (MSC) transplantation following spinal cord injury (SCI) presents some drawbacks, such as an increased incidence of hematological and other malignancies, and tumor metastases, perhaps due to their neorevascularization potential. We remain vigilant and take necessary precautions to address these concerns.
Although stem cell transplantation appears to be safe in the clinical trials performed to date, the risk of possible immune reactions should always be considered [26,72]. Our team closely monitors patients and employs strategies to minimize the likelihood of adverse immune responses.
Timing and delivery methods
The timing of transplantation can have a significant impact on the therapeutic outcome, as the injured spinal cord undergoes various stages of inflammation, secondary injury, and tissue repair [137,138,139,140]. Some studies suggest that transplantation is most effective when carried out 1–2 weeks after injury, while others recommend a therapeutic window of 3–4 weeks following injury. At Visakha Spinetics, we carefully evaluate each patient's condition and determine the optimal timing for stem cell transplantation to maximize the benefits of this therapy.
Another issue regarding stem cell transplantation is the choice of route of administration [26,73]. The selection of a safe and efficacious route of administration is critical to the efficacy of the treatment. Indeed, some routes of administration such as the intramedullary route may be invasive, while other routes such as the intrathecal route may be less efficient because they require many cells. Our experienced team weighs the pros and cons of each delivery method and selects the most appropriate approach for each individual case.
Optimization of transplantation parameters
Furthermore, the development of standardized protocols for stem cell isolation, expansion, and differentiation is crucial for the successful translation of stem cell therapies from the laboratory to the clinic. At Visakha Spinetics, we adhere to rigorous protocols and employ state-of-the- art techniques to ensure the highest quality and consistency in our stem cell preparations.
Another challenge is the need for effective strategies to enhance the survival, integration, and function of transplanted stem cells within the host tissue [18,25,142]. This may involve the use of adjuvant therapies, such as growth factors, neurotrophic factors, or immunomodulatory agents, to promote cell survival and improve the local environment for stem cell integration and differentiation. Our research team is actively exploring these strategies to optimize the therapeutic potential of stem cell transplantation.
Moreover, the development of suitable biomaterials and scaffolds that support cell survival, integration, and function is critical for the successful translation of stem cell therapies from the laboratory to the clinic [25,143,144]. We collaborate with leading researchers and institutions to develop cutting-edge biomaterials and scaffolds that can enhance the efficacy of our stem cell therapies.
There is also a need for the development of reliable and accurate outcome measures to evaluate the efficacy of stem cell therapies in clinical trials [25,145]. This may include the establishment of standardized functional assessments, imaging techniques, and biomarkers that can provide objective measures of treatment success and facilitate the comparison of results across different trials. At Visakha Spinetics, we employ a comprehensive suite of assessment tools and collaborate with leading research institutions to advance the field of stem cell therapy evaluation.
A low rate of neuronal differentiation and a low survival rate are also problems that could occur after cell transplantation [26,74]. Our team is dedicated to addressing these challenges through ongoing research and the development of innovative strategies to enhance the survival and differentiation of transplanted stem cells.
The rise in "stem cell tourism" highlights another significant ethical and safety concern surrounding stem cell therapy, endangering patients' lives and the credibility of legitimate research. Stem cell therapy for a majority of conditions is still at a preclinical phase, yet many clinics worldwide routinely and illegally provide untested and dangerous stem cell therapy to desperate and vulnerable patients, for large sums of money. At Visakha Spinetics, we strictly adhere to ethical guidelines and prioritize patient safety above all else.
The International Society for Stem Cell Research has set guidelines for "ethical, scientifically based and medically and socially responsible" clinical translation of stem cell research, and provides information to the patients to make informed decisions. We align our practices with these guidelines and strive to educate our patients, empowering them to make well-informed choices regarding their treatment.
However, there is still a need for international regulation on the responsible transfer of stem cell lines, and stricter medical malpractice laws directly addressing stem cell therapy, to minimize the unethical exploitation of patients through the use of unapproved therapies. We actively support and advocate for such initiatives to ensure the highest standards of safety and ethics in the field of stem cell therapy.
Preclinical and Clinical Studies Animal models and findings
Preclinical studies have demonstrated the promising potential of stem cell therapy for spinal cord injury (SCI) in animal models. A meta-analysis observed that rats treated with various stem cell types exhibited better motor function scores compared to negative control groups, highlighting
the therapeutic potential of stem cells in SCI. While several types of stem cells can effectively promote functional recovery, factors like stem cell source, administration route, timing, and dosage play a crucial role in determining efficacy.
Network meta-analysis indicated that rats had significantly higher BBB (Basso, Beattie, and Bresnahan) scores, a measure of locomotor function, in stem cell groups compared to negative controls. Subgroup analyses suggested that umbilical cord mesenchymal stem cells (UCMSCs) may be most effective in the first week after transplantation, while adipose-derived mesenchymal stem cells (ADMSCs) may be more effective in later weeks. Higher stem cell doses (≥1 × 10^6) and intralesional transplantation appeared to yield better therapeutic effects. Additionally, subacute phase transplantation (within the first few weeks after injury) may be more beneficial than chronic phase transplantation.
Preclinical evidence demonstrates that stem cells can exert a variety of neuro- and vascular-protective effects at different phases of SCI. Transplanted cells not only reorganize the neuronal network but also have the capacity to reduce local and systemic inflammation, support axonal regeneration and synaptic sprouting, and reduce glial scarring. Different administration routes, such as intravenous, intra-arterial, intrathecal, and intraspinal, have been explored in animal experiments, each with its own advantages and limitations.
Several studies have highlighted the potential of various stem cell types in promoting SCI repair. Embryonic stem cells (ESCs) can differentiate into neurons and glial cells, and ESC-derived neurons have been shown to survive, integrate, and myelinate axons after transplantation into injured spinal cords, resulting in improved functional recovery. Neural progenitor cells (NPCs) can differentiate into oligodendrocytes and neurons, leading to remyelination and functional improvement in animal models.
Mesenchymal stem cells (MSCs), particularly bone marrow-derived MSCs (BM-MSCs), adipose-derived MSCs (AD-MSCs), and umbilical cord- derived MSCs (UC-MSCs), have demonstrated remarkable potential in SCI repair through various mechanisms. BM-MSCs can differentiate into various cell types, exhibit anti-inflammatory properties, and provide trophic support and neuroprotection through the delivery of growth factors like BDNF, VEGF, NGF, GDNF, NT-3, FGF, and EGF. AD-MSCs and UC-MSCs have also shown regenerative effects when administered directly into the lesion area after injury, exerting neurotrophic, anti-inflammatory, anti-apoptotic, and angiogenic effects.
Human clinical trials and outcomes
While preclinical studies have yielded promising results, the translation of stem cell therapy for SCI into clinical practice is still in its early stages. The majority of clinical trials are in phase 1/2, involving small patient cohorts and limited control groups. These trials predominantly focus on severely injured (ASIA A) patients in the chronic stage (>6 months post-injury), as there are currently no effective treatments available for this patient population.
The results of stem cell therapy trials have been mixed, with some reporting no significant recovery, while others have shown promising outcomes. For instance, one study reported that 46% of ASIA A patients recovered to ASIA C (indicating some sensory and motor function preservation) when treated with intrathecal bone marrow-derived mesenchymal stromal cell (BMSC) injection, compared to only 15% in the control group. Another study found that intraspinal BMMNC (bone marrow mononuclear cell) injection was effective when administered within 8 weeks of injury (30% ASIA improvement), but ineffective when transplantation occurred >8 weeks after injury (0% improvement).
The majority of clinical trials are conducted in the chronic phase when the hope for spontaneous recovery is minimal. While some studies have reported no improvement on the ASIA impairment scale, others have shown recovery rates as high as 100%. However, even in trials that did not report ASIA scale improvement, some degree of improvement was observed in other assessments, such as somatosensory evoked potentials (SEP) or motor evoked potentials (MEP). Additionally, some reports have analyzed matched-control patients, with the recovery rate reportedly higher in stem cell treatment groups.
It is important to note that the results of stem cell therapy trials can vary due to factors such as the type of stem cells used, the administration route, the timing of transplantation, and the severity of the injury. Ongoing research and larger, well-controlled clinical trials are necessary to further evaluate the safety and efficacy of stem cell therapy for SCI and to optimize treatment protocols.
At Visakha Spinetics, we closely follow the latest developments in preclinical and clinical research on stem cell therapy for SCI. Our team of experts carefully evaluates the available evidence and incorporates the most promising and safe techniques into our treatment protocols. We prioritize patient safety and strive to provide personalized, cutting-edge stem cell therapies tailored to each individual's unique needs and circumstances.
Future Directions and Emerging Technologies Biomaterial scaffolds and tissue engineering
At Visakha Spinetics, we are at the forefront of exploring innovative biomaterial scaffolds and tissue engineering approaches to enhance the efficacy of stem cell therapies for spinal cord injury (SCI) repair. Recent advancements in medicine, biology, and biomaterials engineering have paved the way for new regenerative therapies, contributing to the possibility of healing traumatic SCI and preventing further neurodegeneration [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19].
Biomaterial scaffolds play a crucial role in generating specific microenvironmental cues in a three-dimensional (3D) controlled fashion, enhancing the survival, infiltration, and differentiation of stem cells. These scaffolds are used for spinal cord regeneration following injury, providing a supportive framework for cell growth and tissue repair.
We are actively exploring the use of hydrogels, electrospun fibers, and 3D printing techniques to develop advanced biomaterial scaffolds tailored for spinal cord regeneration. Hydrogels offer biocompatibility and the ability to mimic the extracellular matrix of tissues, making them an attractive option for stem cell delivery and support [98,99]. Electrospinning allows us to create nano- to micron-scale fibers with controlled morphological characteristics and porosity, providing a suitable environment for nerve regeneration [83,107]. Additionally, 3D printing technology enables the fabrication of individualized scaffolds that match the precise structure of the spinal cord injury, offering a customized microenvironment to stimulate and guide axon regeneration [108,109,110].
The advancements in biomaterial technology, combined with stem cell therapy or other regenerative therapies, can now accelerate the progress of promising novel therapeutic strategies from bench to bedside. By combining exogenous cells and scaffolds to form live scaffolds, we can expect synergistic effects that enhance the therapeutic potential of stem cell transplantation.
Combinatorial approaches and adjunct therapies
At Visakha Spinetics, we recognize that successful future therapies will require a combination of biomaterial scaffolds and other synergistic approaches to address the persistent barriers to spinal cord regeneration, including glial scarring, loss of structural framework, and biocompatibility concerns. We are actively exploring combinatorial approaches and adjunct therapies to enhance the efficacy of stem cell transplantation.
One promising avenue is the combination of gene therapy and stem cell transplantation. In this approach, genes are delivered to the injury site to promote stem cell survival and differentiation. Genetically modified stem cells, such as neural stem cells and mesenchymal stem cells engineered to express neurotrophic factors like brain-derived neurotrophic factor (BDNF), neurotrophin-3, and glial cell-derived neurotrophic factor (GDNF), offer a promising avenue for developing effective SCI treatments [46,47].
We are also investigating the synergistic effects of stem cell transplantation and physical therapy. Stem cells not only provide a source of cells that can differentiate into cells needed for repair and regeneration but also secrete growth factors and other molecules that promote the survival
and differentiation of endogenous cells, enhancing the effects of physical therapy [62,63,64,65,68,69,70,71,72,73,74,75,76,77].
Additionally, we are exploring the potential of combining stem cell therapies with nanoparticles (NPs) for SCI treatment. Animal models have shown that the combination of NPs and stem cells can have a positive impact on neuroprotection and neuroregeneration [91,92,95,96,97,98]. By carefully selecting therapeutic molecules and types of NPs, we aim to exacerbate the neurorestorative effects of stem cells and translate these findings into clinical trials.
Ethical and regulatory considerations
As we advance in the field of stem cell therapy for SCI, we remain committed to upholding the highest ethical and regulatory standards. We acknowledge the ethical concerns associated with embryonic stem cell research and the potential risks of gene therapy [2,15,20,25,33,50].
To address these concerns, we have embraced the use of induced pluripotent stem cells (iPSCs), which can be generated from a patient's own cells, minimizing the risk of immune rejection [46,47]. We also ensure rigorous evaluation of the safety and potential risks associated with gene therapy, ensuring that the benefits outweigh the potential harm.
We prioritize obtaining informed consent from donors and patients, protecting confidentiality, and minimizing medical risks associated with procedures such as oocyte retrieval [15,20,25,33]. We also recognize the importance of evaluating comprehension and addressing potential downstream uses of stem cell derivatives.
As we move towards clinical trials, we collaborate with research ethics bodies to ensure that ethical requirements, such as scientific validity, fair participant selection, favorable risk-benefit ratio, independent review, informed consent, and respect for participants, are adequately considered [2,15,20,25,33,50].
We encourage the leaders in the field of human spinal cord repair to work together to produce a consensus and develop clear protocols and atrial network. The detailed clinical assessment of patients with SCI and the indications and suitability of the patient for surgery are critical assessment tools that need to be developed and standardized [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50].
At Visakha Spinetics, we remain committed to advancing the field of stem cell therapy for SCI while upholding the highest ethical and regulatory standards, ensuring the safety and well-being of our patients, and contributing to the development of effective and accessible treatments for those affected by spinal cord injuries.
