Cell morphology. a The cells were used to form EBs 3 days after passage. b hES cells formed EBs after suspension culture for 3 days. c The EBs were transferred to standard culture plate for 2 days and some EBs attached. The morphology of EBs attached for 4 (d) and 6 (e) days in EB medium. The cells were stimulated with 1 pM BMP4 in EB medium on days 4 (f) and 6 (g). Scale bar, 300 μm
