白血病抑制因子(LIF)是维持小鼠胚胎干细胞多能性不可缺少的因子。还需要饲养层和血清来维持未分化状态,然而,临床应用需要消除此类动物来源的材料。因此,需要更可靠的ES细胞培养技术。我们使用3D回转器在模拟微重力下培养小鼠ES细胞。我们使用无饲养层和无血清培养基,不含LIF。在这里,我们表明,模拟微重力允许新的无LIF和动物源性材料的小鼠ES细胞培养方法。
Leukemia inhibitory factor (LIF) is an indispensable factor for maintaining mouse embryonic stem (ES) cell pluripotency. A feeder layer and serum are also needed to maintain an undifferentiated state, however, such animal derived materials need to be eliminated for clinical applications. Therefore, a more reliable ES cell culture technique is required. We cultured mouse ES cells in simulated microgravity using a 3D-clinostat. We used feeder-free and serum-free media without LIF. Here we show that simulated microgravity allows novel LIF-free and animal derived material-free culture methods for mouse ES cells.
