Where Generations Converge: Germ Lines and Body PlansAs embryos develop, a hierarchy of developmental events is expressed in the progressive differentiation of cell types, regionalization of embryos, and establishment of morphological differences between regions. Perhaps the most fundamental of such events are the segregation of body cells from germ cells and the laying down of the body plan.作者: Dappled 時間: 2025-3-24 18:23
