Differentiation potential of zebra fish iPS-like cells in vivo. PKH26-labeled F-ziPSCs (passage 22) and PKH26-labeled zFF cells (passage 10) were transplanted with approximately 300 cells to host blastulae. The resultant chimeras were analyzed by microscopy. For the PKH26-labeled F-ziPSCs (red): (A) bright field micrograph, (B) red fluorescent micrograph, (C) merge between bright and fluorescent optical fields, and (D-H) different distributions of PKH26-labeled donor cells in different stages, in which the chimeras were analyzed by microscopy at 2 (D-G) and 5 days post-fertilization (H) (ey, eye; ht, heart). For the PKH26-labeled zFF cells (red): (I-L) the zFF cells did not migrate. The scale bars in A-E and I-L represent 200 μm and those in F-H represent 300 μm.
