目的:为保持胚胎干细胞的高度未分化状态,饲养层细胞成为胚胎干细胞体外培养中不可缺少的条件。
AIM: Feeder layer cells are the necessary condition to prevent the differentiation of embryonic stem cells cultured in vitro.
胚胎干细胞单独存放在皮氏培养皿中,为一切做好准备,这使它们成为研究和治疗的独特工具。
Alone in their Petri dishes, embryonic stem cells are primed for anything, making them unique tools for research and therapy.
胚胎干细胞的研究备受争议,原因是获得能够发育成为几乎人体所有组织的细胞,有损于人类胚胎。
Embryonic stem cell research is controversial because human embryos are destroyed in order to obtain the cells capable of developing into almost every tissue of the body.
