Phenotypic characterization and differentiation of pMSC. Chondrogenic (A), osteogenic (B) and adipogenic (C) differentiation of pMSC, revealed by Alcian Blue, Alizarin Red and Oil Red staining, respectively. Scale bar = 100 μm. Flow cytometry analysis of the pMSCs’ surface antigen expression (D). Most cultured cells were positive for surface antigens typically expressed by mesenchymal stem cells: CD105+, CD29+, CD73+, CD90+ and negative for non-mesenchymal CD34- and CD45- markers. Blue graphs represent negative control (isotypic immunoglobulins); pink graphs – experimental samples.
