Mouse embryonic stem (ES) cells can differentiate in culture to late stages of many cell lineages. I have found culture conditions that are favorable for development in vitro of ES cells into hematopoietic cells at a stage equivalent to day 11-14 of fetal liver development. I describe here: (1) the growth conditions necessary for maintenance of ES cells in an undifferentiated state, and the conditions that allow differentiation of cystic embryoid bodies that contain precursors of most hematopoietic cell lineages, including lymphoid cells; (2) the development of lymphoid vessels from ES fetuses in vivo; (3) the characterization of lymphoid, erythroid, megakaryoid, and myeloid cells from ES fetuses; and (4) the cloning of cell lines representing lymphoid, myeloid lineage cells from differentiated ES cells.
小鼠胚胎干细胞(ES细胞)在培养中可分化至许多细胞谱系的后期阶段。我已发现有利于ES细胞在体外发育为造血细胞的培养条件,该阶段相当于胎儿肝脏发育的第11 - 14天。我在此描述:(1)维持ES细胞处于未分化状态所需的生长条件,以及允许含有大多数造血细胞谱系(包括淋巴细胞)前体的囊性胚状体分化的条件;(2)ES胎儿在体内淋巴血管的发育;(3)ES胎儿来源的淋巴细胞、红细胞、巨核细胞和髓细胞的特征;以及(4)从分化的ES细胞中克隆代表淋巴细胞、髓细胞谱系细胞的细胞系。
