Midsagittal sections of V. globator embryos in successive stages of inversion. Stained sections were analyzed by light microscopy. (A) An embryo 5 min to 10 min before the initiation of inversion; details are shown in Figure 6B, C, D, E, F. (B) An embryo 3 min to 5 min after the initiation of inversion. (C) An embryo 5 min to 10 min after the initiation of inversion; details are shown in Figure 7. (D) An embryo 10 min to 15 min after the initiation of inversion; details are shown in Figure 8A, C. (E) An embryo 20 min to 25 min after the initiation of inversion; details are shown in Figure 8D, E, F. (F) An embryo 30 min to 35 min after the initiation of inversion; details are shown in Figure 8B. (G) An embryo 35 min to 40 min after the initiation of inversion; details are shown in Figure 9. (H) An embryo 5 min to 10 min after the end of inversion (that is, 55 min to 60 min after initiation of inversion); details are shown in Figure 10A, B, C, D, E, F, G. Rectangles, ovals and arrows indicate details shown in other figures as described in the legend to Figure 3; a broken line refers to a detailed view that is perpendicular to the image plane. Scale bars: 20 μm.
