Identification of the essential role of Dvr1 in C&E cell movements using a cell-tracing strategy. (A–P) Tracking cell movements in C&E using UV-mediated photoactivation. At the one-cell stage, the embryos were injected with either 100 pg mRNA coding for Kaede protein plus dvr1 control morpholino or kaede mRNA plus dvr1/setdb2 morpholinos. Embryos were labeled by UV radiation at the shield stage and analyzed at the tail-bud stage. Dorsal mesendodermal cells in control (A,B, n=13), dvr1 mo^ATG (E,F, n=21), dvr1 mo^SB (I,J, n=10) and setdb2 mo (M,N, n=14). Lateral mesendodermal cells in control (C,D, n=13), dvr1 mo^ATG (G,H, n=22), dvr1 mo^SB (K,L, n=10) and setdb2 mo (O,P, n=18). (Q) Statistical analysis of anterior migration of labeled dorsal mesendodermal cells and dorsal migration of lateral mesendodermal cells. All images were lateral views. Asterisks indicate statistically significant differences (***, P<0.001; ****, P<0.0001). V, ventral side. D, dorsal side.
