|---|---|---|---|---|---|
| Summary | The process by which an embryo forms and develops, marking a time of rapid cell proliferation, specification, and differentiation. Embryogenesis in C. elegans takes about fourteen hours at 22 degrees C, starting with fertilization of the oocyte with self-sperm from the hermaphrodite or sperm from a male. During the first two hours, the zygote forms and early cleavages establish the embryonic axes. Somatic and germ-line founder cell fates are also determined. During the next five hours, most cell proliferation completes, the embryo undergoes gastrulation, and cell differentiation and organogenesis begins. Cell differentiation, organogenesis and morphogenesis are completed during the final stage of embryogenesis. The nervous system becomes active and muscles are stimulated during this last stage, resulting in the embryo twitching within its egg shell and eventually hatching as an L1 larva. | ||||
