title: Ecto-mesenchymal stem cells from facial process: potential for muscle regeneration.
abstract: Ecto-mesenchymal stem cells (EMSCs) originate from the cranial neural crest and participate in the formation of tooth, salivary, and muscle in early development stage. The transplantation of EMSCs, a potential source of myoblast stem cell, might improve muscle regeneration. The purpose of this study was to explore whether EMSCs have the potential to differentiate and display a myogenic phenotype in vitro the in vitro. Here, we characterized the EMSCs isolated from the facial process, and p75 + EMSCs were collected by a FACS calibur flow cytometer. In vitro, p75 + EMSCs induced by DMSO can accumulate and fuse into multinucleated myotubes and further differentiate into the skeletal muscle cells in form of cell sheet. Functional myoblast phenotypes of p75 + EMSCs were found in vivo model of muscle injury. The remarkable ability of stem cells to regenerate skeletal muscle indicated their potential role in the cell therapy and tissue engineering of the skeletal muscle.
