Fig. 10

Fates of micromere 3c, and its subclones, during gastrulation and organogenesis. Images of live embryos, with dextran and diI-labeled 4d, 3c, or 3c subclones, as indicated. Animal pole is up in a and b. Anterior is up in c–t. a, b Dorso-lateral views of early epiboly-stage embryos. c, d Ventral views of early epiboly-stage embryos. Corresponding ventral views of late epiboly-stage embryos are shown in e-f, g-h, i-j at successive stages of development with different combinations of fluorescence and/or DIC layers shown. k, l Corresponding ventral and posterior views of an elongating embryo. m, n Ventral views of embryos during elongation. Corresponding right-lateral views of embryos during organogenesis o-p, s-t. Note green background fluorescence is higher in s, t. (Q-R) Corresponding oblique, ventro-lateral views of an embryo during organogenesis. nt neurotroch, rtc right terminal cell, pvb posterior velar band. All other labels are the same as those used in Figs. 3 and 6. Scale bar equals 50 μm
