Fig. 3 Differential requirement of myeloid-expressed transcription factor on the expression of c/ebp1, pu.1 and runx1. Whole-mount in situ hybridization with probes shown at bottom right of each panel. Injected morpholinos are indicated at top right. All embryos are around 24 hpf and lateral view; anterior is left. (A–D) lyz expression was inhibited in pu.1 MO-, runx1 MO- and c/ebp1 MO-injected embryos. (E–G) The expression of c/ebp1 in myeloid cells was suppressed in pu.1 morphants, but not in runx1 morphants. (H–J) The runx1 expression in myeloid cells (red arrowheads; H and J), but not in the ICM and Rohon-beard cells, was inhibited in pu.1 morphants, while injection of c/ebp1 MO did not affect runx1 expression. (K–M) pu.1 expression in myeloid cells was comparably detected in uninjected-, runx1 MO-injected and c/ebp1 MO-injected embryos.
