Fig. 7
The expression domains of etv2 and tal1 are truncated in Tcf7l1 deficient embryos. ((A)–(D)) Etv2 and ((E)–(H)) tal1 expression at the 8 s stage in control, Tcf7l1a, Tcf7l1b, and Tcf7l1 deficient embryos. Etv2 and tal1 expression are slightly more truncated in Tcf7l1a deficient embryos compared to Tcf7l1b deficient embryos. The effects on etv2 and tal1 expression at this stage in Tcf7l1 deficient embryos is equivalent to Tcf7l1a deficient embryos. Images are dorsal with anterior up. Arrows in (A)–(H) indicate distance between the anterior and posterior limits of expression.
