Morphology of hESC colonies cultured in different conditions. a hESC-1 showed a differentiated state after five passages cultured in XF-HFF/CDM conditions. b hESC-1 maintained an undifferentiated state cultured in XF-HFF/CDM conditions after 40 passages. c Morphology of hESC-1 cultured in XF-HFF/HS medium after five passages is elongated with a high nucleus/cytoplasm ratio, but a low propagation rate. d Morphology of hESC-1 cultured on HS-matrix in CDM medium after five passages is elongated with a low nucleus/cytoplasm ratio and propagation rate. e Morphology of hESC-1 cells on XC-HFF in KSR medium after 45 passages was still undifferentiated with a high nucleus/cytoplasm ratio and high propagation rate. Scale bar represents 50 μm
