hand2 overexpression limits expression of blood and vessel genes within the ALPM. (A-L) In situ hybridization depicts expression of (A,B) scl, (C,D) etsrp, (E,F) pu.1, (G,H) mef2cb, (I,J) nkx2.5 and (K,L) gata4 in (A,C,E,G,I,K) nontransgenic embryos and (B,D,F,H,J,L) Tg(hsp70:hand2) embryos following heat shock at 10hpf. Dorsal views, anterior upwards, at (A-J) 12 somites and (K,L) 10 somites. Overexpression of hand2 results in (A-F) decreased distribution of scl, etsrp and pu.1 expression, as well as (G,H) increased expression of mef2cb. By contrast, expression of (I,J) nkx2.5 and (K,L) gata4 appear relatively normal in hand2-overexpressing embryos at these stages.
