Specific induction of epigenetic regulatory genes by C/ebpαDN. (A-H) WISH analyses of a panel of epigenetic regulators involved in the HSC maintenance and self-renewal at 22 hpf. The arrows indicate the specific induction of bmi1 (A-B), rae28 (C-D), prdm3 (E-F), and prdm16 (G-H) transcripts in the ICM or PBI region.
