TGFβ1 and TGFβ3 Are Required for Specification of HSCs

(A) Expression of runx1 in wild-type, tgfb1, tgfb2, and tgfb3 morphants.

(B) Expression of kdrl in wild-type, tgfb1, tgfb2, and tgfb3 morphants.

(C) Expression of dll4 in wild-type, tgfb1, tgfb2, and tgfb3 morphants.

(D) Expression of dlC in wild-type, tgfb1, tgfb2, and tgfb3 morphants. All samples were analyzed at 28 hpf.

(E-G) Maximum projections of itga2b:GFP; Kdrl:HRas-mCherry transgenic embryos in (E) uninjected, (F) tgfb1 morphants, and (G) tgfb3 morphants at 48 hpf. The images show part of the trunk DA and white arrowheads denote itga2b:GFP⁺ (green), kdrl:HRas-mCherry⁺ (magenta) HSPCs.

(H) HSPCs counts in the entire trunk region of uninjected, tgfb1, and tgfb3 morphant itga2b:GFP; Kdrl:HRas-mCherry transgenic embryos at 48 hpf (p value is indicated on the graph, n = 10 for each of the conditions).

(I-K) Expression of rag1 in the thymus at 4 dpf (red arrowheads) in (I) wild-type, (J) tgfb1 morphants, and (K) tgfb3 morphants.

(L) Expression of efnB2a in wild-type, tgfb1, and tgfb3 morphants.

(M) Expression of gata2b in wild-type, tgfb1, and tgfb3 morphants. The numbers of embryos are shown in each panel as the number of embryos with phenotype/total number analyzed.
