Zebrafish dpr1 and dpr2 can be regulated by bone morphogenetic protein (BMP) signaling. Embryos are at sphere stage. A-F: Zebrafish dpr1 expression. G-L: Zebrafish dpr2 expression. Injected RNAs are indicated in the figure. C,D,I,J: Embryos injected with nog RNA have ectopic dpr1 and dpr2 expression. E,F,K,L: Embryos injected with bmp2b RNA have reduced expression of dpr1 and dpr2. A,C,E,G,I,K are lateral views. B,D,F,H,J,L are animal views. Dorsal is to the right.
