Adult tissues have amazing regeneration potential. However, the cell sources involved in regeneration have not been clearly identified. Recently, we identified a novel type of multipotent stem cells from blood vessels, termed multipotent vascular stem cells MVSCs. MVSCs can differentiate into various cell types including neurons and Schwann cells. Another recently identified adult stem cell is very small embryonic-like stem cells VSEL-SCs. This type of stem cells can be isolated from blood after cytokine mobilization of bone marrow cells, and can differentiate into specific cell types in all three germ layers. We investigate whether MVSCs and VSEL-SCs can promote the regeneration of peripheral nerve following trauma injuries. Transplanted MVSCs in nerve conduits differentiate into perineural cells and pericytes, thus promoting axon growth and nerve regeneration. This project addresses the issues in several focus areas, including regenerative medicine, nanomedicine and biomaterials, advanced prosthetics and trauma treatment.
