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，乙醇会干扰分裂、增殖，影响生长和分化，且在胚胎发育的过程中，妨碍成熟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。

But perhaps the scariest fact is that even after one night of 4-5 hrs of sleep, your natural killer cells, which stop cancer cells from proliferating in your body drop by 70%.

Hair colour is controlled by whether continually multiplying pools of McSCs within hair follicles get the signal to become mature cells that make the protein pigments responsible for colour.

头发颜色的控制取决于毛囊内不断增殖的McSC是否收到信号，变成成熟，从而产生不同颜色的蛋白质色素。

Other activated B-cells go to the center of a primary follicle in the lymph node and they differentiate into B-cells called centroblasts and start to proliferate or divide.
