很早以前，有人推测造血干细胞和血管干细胞来自共同的干细胞-血液血管母细胞。

The first passage of YS-MSCs which grew in good condition was obtained, and adipogenic differentiation of YS-MSCs was induced by dexamethasone and insulin, and angioblast was induced by vascular endothelial growth factor and basic fibroblast growth factor.

取生长状态良好的第1代细胞，以地塞米松、胰岛素定向诱导卵黄囊间充质干细胞向脂肪细胞方向分化；以血管内皮生长因子和碱性成纤维细胞生长因子体外诱导其向血管内皮细胞方向分化。

BACKGROUND: Compared with adult mesenchymal stem cells, yolk sac-derived MSCs of early embryo have stronger self-renewal capacity and plasticity. Moreover, they could differentiate into angioblast and hemopoietic stem cells during embryonic development and trigger embryonic angiogenesis and hemopoietic tissue development.

背景：与成体间充质干细胞相比，来源于早期胚胎的卵黄囊间充质干细胞有更强的自我更新能力和可塑性，且在胚胎发育过程中可分化为成血管细胞和造血干细胞，启动胚胎血管发生和造血组织发育。
