Hypothesis
Can mesenchymal stem cells (MSCs) and their extracellular vesicles (MSC-EVs) effectively repair the blood-spinal cord barrier (BSCB) following spinal cord injury (SCI)?
Conclusion
Both MSCs and MSC-EVs show significant potential in repairing the blood-spinal cord barrier and improving recovery after spinal cord injury.
Supporting Evidence
- MSCs enhance BSCB integrity by improving endothelial–pericyte association.
- MSC-EVs replicate many of MSCs’ therapeutic effects and offer a promising cell-free alternative.
- Preclinical studies show that both MSCs and MSC-EVs can reduce BSCB permeability.
- MSC therapy is advancing in clinical trials, while MSC-EV therapies require further optimization.
Takeaway
This study shows that special cells called mesenchymal stem cells and tiny bubbles they make can help fix the barrier in the spine after an injury, which helps people heal better.
Methodology
The review discusses various studies on the effects of MSCs and MSC-EVs on BSCB integrity and functional recovery in spinal cord injury models.
Limitations
MSC-EV therapies require further optimization in production, dosing, and delivery protocols.
