Abstract:
Animal models have been used in preclinical research to examine potential new treatments for spinal cord injury (SCI), including mesenchymal stem cell (MSC) transplantation. MSC transplants have been studied in early human trials. Whether the animal models represent the human studies is unclear. This systematic review and meta-analysis has examined the effects of MSC transplants in human and animal studies. Following searches of PubMed, Clinical Trials and the Cochrane Library, published papers were screened, and data were extracted and analysed. MSC transplantation was associated with significantly improved motor and sensory function in humans, and significantly increased locomotor function in animals. However, there are discrepancies between the studies of human participants and animal models, including timing of MSC transplant post-injury and source of MSCs. Additionally, difficulty in the comparison of functional outcome measures across species limits the predictive nature of the animal research. These findings have been summarised, and recommendations for further research are discussed to better enable the translation of animal models to MSC-based human clinical therapy.
Insights
Mesenchymal stem cell (MSC) transplants show promise for spinal cord injury (SCI) in both humans and animals. However, discrepancies in study designs limit the predictive value of animal models for human clinical therapy.
Area of Science:
- Regenerative Medicine
- Neuroscience
- Translational Research
Background:
- Animal models are crucial for preclinical research into spinal cord injury (SCI) treatments.
- Mesenchymal stem cell (MSC) transplantation is a promising therapeutic strategy investigated in both animal models and early human trials.
- The translational validity of animal models for human SCI studies remains uncertain.
Purpose of the Study:
- To systematically review and meta-analyze the effects of MSC transplantation in human and animal studies of spinal cord injury.
- To identify discrepancies between animal models and human studies of MSC transplantation for SCI.
- To assess the predictive value of animal research for human clinical therapy.
Main Methods:
- Systematic literature search of PubMed, Clinical Trials, and Cochrane Library databases.
- Screening of published papers and extraction of relevant data.
- Meta-analysis of outcomes from human and animal studies involving MSC transplantation for SCI.
Main Results:
- MSC transplantation was associated with significant improvements in motor and sensory function in human patients.
- MSC transplantation significantly enhanced locomotor function in animal models of SCI.
- Key discrepancies were noted between human and animal studies, including timing of transplant and MSC source.
Conclusions:
- While MSC transplantation shows therapeutic potential for SCI, significant differences exist between animal models and human studies.
- Challenges in comparing functional outcomes across species hinder the direct translation of animal research findings.
- Recommendations are provided to improve the design of future research to enhance the predictive accuracy of animal models for human MSC-based SCI therapy.
