Researchers from University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System used stem cells to regenerate corticospinal injury damage, according to newswise.
Nature Medicine published the study.
Here are five observations:
1. The researchers directed stem cell-derived neurons to regenerate tissue in rats' damaged corticospinal tracts.
2. The study involved grafting of multipotent neural progenitor cells into spinal cord injury sites of rates.
3. The stem cells formed functional synapses, enhancing forelimb movements.
4. Researchers have never successfully regenerated the corticospinal projection.
5. Before testing the theory in humans, the researchers must establish long-term safety and figure out the best type of human neural stem cell to use.
