Still images of WT and bbp embryos at the 1000-cell stage (A, B), 50% epiboly (A′, B′), and 50% epiboly at the burst (A″, B″). bbp embryos constrict just as they reach 50% epiboly. (C and D) Selected frames from time-lapse movies of WT and bbp embryos showing that the constriction occurs rapidly once the embryos have reached 50% epiboly.
