[单项选择]人类胚胎干细胞是人类胚胎发育早期--囊胚中未分化的细胞。囊胚外表是一层扁平细胞,可发育成胚胎的支持组织(如胎盘等);中心的腔称为囊胚腔,腔内侧有内细胞群。内细胞群在形成内、中、外三个胚层时开始分化,内胚层分化形成肝、肺和肠等,中胚层分化形成骨骼、血液和肌肉等,外胚层分化形成皮肤、眼睛和神经系统等。由于内细胞群能发育成完整的个体,因而这些细胞被认为具有伞能性。成人身上也有干细胞,主要分布于骨髓、血液、大脑、胰腺等处,比如骨髓和血液中就有造血干细胞。但是,这些成年干细胞非常稀少,较难分离和纯化。它们的作用基本上是确定的,例如骨髓中的造血干细胞在体内环境下的使命就是分化成各种血液细胞。下列对"人类胚胎f细胞"这一概念的理解,符合文意的一项是()。
