Differentiation Potential of Mesenchymal Stem Cells and Stimulation of Nerve Regeneration

详细

Mesenchymal stem cells (MSCs) are widely used in experimental research on cell therapy intended for the stimulation of repair processes in damaged tissues and organs. The present review summarizes the results of studies devoted to the possible directions of MSC differentiation after the transplantation of these cells into damaged nerves or special engineered structures of biological and artificial biodegradable materials that join the ends of a damaged nerve (nerve conduits). Data on exogenous MSC differentiation into Schwann cells, pericytes, smooth muscle cells, endotheliocytes, and other cell types are presented. Methods for preliminary MSC differentiation in vitro and examples of beneficial effects of these cells transplanted into damaged conductive nerves on nerve regeneration are given. The fate of exogenous MSCs placed into an unnatural biological niche remains poorly characterized and requires further studies, as emphasized in the review.
