If they're not the follicle that is trying to mature that month, they just stay basically frozen in time in a state of meiosis.

但在某些组织中，它们将继续分裂产新的干细，而后再分化成熟以跟上身体长发育需求。

In FAS, ethanol interferes with cell division and proliferation, cell growth and differentiation and with the migration of mature cells to their final location in the developing embryo which affects the development of various fetal tissues, including the brain.

在FAS中，乙醇会干扰细分裂、增殖，影响细长和分化，并且在胚胎发育的过程中，妨碍成熟细迁移到它们最终的部位，这会影响胎儿各种组织的发育，其中包括大脑。
