npas4l is expressed in both PAA progenitors and angioblasts. (A,B) Analysis of the expression patterns of nkx2.5 and npas4l in the pharynx at the indicated stages by in situ hybridization. The asterisks indicate the expression of npas4l in the lateral dorsal aortae. (C) Double in situ hybridization of npas4l (red) and nkx2.5 (blue) expression at 28 and 36 hpf. (D,E) Expression analysis of nkx2.5 (D) and npas4l (E) in embryos injected with 3 ng nkx2.5 MO. The expression of nkx2.5 but not npas4l was clearly increased in nkx2.5 morphants.
