Human iPSCs and basic characterization of iPSC-derived mesenchymal stem cells (iPSC-MSCs). (A) Morphology and alkaline phosphatase (AP) activity of iPSC colony. (B) Immunostaining of human iPSCs for the pluripotent markers Oct4, Nanog, TRA-1-81 and SSEA4. (C) Morphological changes during MSC differentiation via embryonic body cultivation. (D) MSC surface marker characterization by FACS analysis. (E) Multilineage differentiation of iPSC-derived MSCs. Oil red O, von Kossa, and Myo D (immunostaining) were used to assess the multilineage differentiation of iPSC-derived MSCs for adipogenesis, osteogenesis and myogenesis, respectively.
