Embryoid bodies generated from murine iPSC and morphological appearance of iPSC-cells derived by treatment with various growth factors. (A) EBs derived from murine iPSC (B) iPSC-cells derived by exposure to RA alone (C) iPSC-cells derived by exposure to bFGF and RA (D) iPSC-cells derived by exposure to TGF-beta1 and RA (E) iPSC-cells derived by exposure to TGF-beta3 and RA (F) iPSC-cells derived by exposure to BMP-2 and RA. The round cells within each preparation probably represent undifferentiated cells. Details for generation of each cell population are outlined in the text in materials and methods section. Original magnifications 200X.
