Heart of glass/heg1 and santa/krit1 embryos display similar HSC phenotypes to silent heartembryos. Expression of cmyb (A-C) or runx1 (D-F) in HSCs in the AGM region (A-F) or CHT (G-I) in control MO (A,D,G), heg1MO (B,E,H), and krit1MO (C,F,I) injected embryos. Expression of rag1 in the thymus in control MO (J), heg1MO (K), krit1MO (L) injected embryos. (A-F) Arrows mark AGM HSCs, 36 hpf. (G-I) Arrows mark CHT, 2 dpf. (J-L) Arrows mark T cells, 4 dpf. Anterior is to the left and dorsal is up.
