Differentiation potential of zebra fish iPS-like cells in vitro. (A) Embryoid bodies (EBs) derived from F-ziPSCs (passage 15). (B) Differentiated cell types from the EBs after attaching to a culture plate, showing a flat cell (arrow) and a neuron-like cell (asterisk). (C) Star-shaped cells. (D) Results by RT-PCR analyses of the three differentiation markers (nestin, brachyury, and gata4) for the three germ layers (At least three independent experiments were conducted for these results). (E) Nestin expression in the EBs formed from F-ziPSCs (passage 15) determined by immunofluorescence. The scale bars in (A-C) represent 50 μm and that in (E) represents 200 μm).
