胚胎干细胞 (Embryonic stem cell,ES)是从着床前的内细胞团 (ICM)或原始生殖细胞 (PGCs)经体外分离培养而建立的克隆细胞系。ES细胞的特点是只生长、不分化。并保持早期胚胎发育的多能性。人 ES细胞既具有其他哺乳动物 ES细胞的一般特性 ,又有自己的特殊性。人 ES细胞系的建立及开发利用具有重要意义
Embryonic stem cells (ES) are clonal cell lines established by in vitro isolation and culture from pre-implantation inner cell mass (ICM) or primordial germ cells (PGCs). ES cells are characterized by growth and undifferentiation. And maintain the pluripotency of early embryonic development. Human ES cells not only have the general characteristics of other mammalian ES cells, but also have their own particularity. The establishment and development and utilization of human ES cell line is of great significance
