The pervious study has showed that placenta mesenchymal stem cells (PMSCs) can differentiate into bone, cartilage, and muscle and adipose mesenchymal stem cells.


To investigate the differentiation of PMSCs into epidermal cells in vitro.


PMSCs were isolated and cultured and the surface antigen was detected by flow cytometry.


Isolated PMSCs were positive for the markers CD105, CD29 and CD44 and negative for typical hematopoietic and endothelial markers CD34, CD45, CD106 and HLA-DR. The morphology of induced cells was obviously changed. Immunohistochemistry stain analysis showed positive for epidermal-specific markers like CK19 and CK10. The PMSCs have the capability to differentiate into epidermal cells in vitro. The placenta may prove to be a useful source of mesenchymal stem cells in skin tissue engineering and stem cells study.
