Fig. 4 c/ebp1, pu.1 and runx1 coordinately regulate lyz expression. All embryos are around 24 hpf and lateral view; anterior is left. (A) Injection of mRNA mixture (runx1 [100 pg] + pu.1 [10 pg] or runx1 [100 pg] + c/ebp1 [100 pg]) did not affect lyz expression compared to uninjected embryos. lyz expression in the ICM (orange arrowhead) was weakly induced in the embryos injected with mRNA mixture (c/ebp1 [100 pg] + pu.1 [10 pg]). Injection of mRNA mixture (runx1 [100 pg] + c/ebp1 [100 pg] + pu.1 [10 pg]) strongly induced lyz expansion in the ICM (red arrowhead). (B) The expression of erythroid markers gata1 and band3 was comparable in both uninjected- and triple mRNA-injected embryos.
