Fig. 2. Caenorhabditis elegans cpl-1(ok360) embryos fail to undergo morphogenesis and accumulate large cytoplasmic vesicles. (A-D) Development of the wild-type embryo: 2-cell (A); 12-cell (B); 100-cell (C); and threefold (D) stage embryos. (E-I) Development of cpl-1(ok360) embryo: 2-cell (E), 8-cell (F); 28-cell (G) 100-cell (H); and terminal (I) stage embryos. Images B and F; C and G; and D and H; were taken at 30 minutes, 120 minutes and 7 hours, respectively, after division to the 2-cell stage. (I) Terminal mutant phenotype image was taken 15 hours after that in H. Arrowheads indicate abnormally large cytoplasmic vesicles in cpl-1(ok360) embryos. Each embryo is approximately 50 µm in length.
