Identification of MSCs. (a) Flow cytometry was used to identify phenotypic surface markers of MSCs. All MSCs from different donors were positive for CD29, CD73, and CD105 but negative for CD14, CD45, and HLA-DR, confirming the typical MSC phenotype. (b) Osteogenic, chondrogenic, and adipogenic differentiation were successfully induced.
