aldh1a2um22 and aldh1a2i26 mutant embryos retain some endoderm gene expression at 48 and 72 hpf.
DMSO treated wild type embryos (A, E, I, M, Q), DEAB-treated wild type embryos (B, F, J, N, R), embryos from an incross of aldh1a2um22 heterozygotes (C, G, K, O, S) and embryos from an incross of aldh1a2i26 heterozygotes (D, H, L, P, T) were assayed for expression of pdx1 at 48 hpf (A–D), sid4 at 48 hpf (E–H), carbA at 72 hpf (I–L), ifabp at 72 hpf (M–P) and transf at 72 hpf (Q–T). Gene expression is observed in the intestine (open arrows), liver (black arrowheads) and pancreas (black arrows). Embryos are in dorsal view with anterior to the left. See Table 2 for quantification.
