Factors for extending the ability of isolated pluripotent stem cells to generate extraembryonic lineages in vivo, following in vitro culture, herein, chemical extenders of pluripotency (CEP). Methods of extending the ability of a pluripotent cell to generate embryonic and extraembryonic lineages. The cell to be reprogrammed is contacted with effective amounts of the CEPs for a sufficient period of time to reprogram the cell into a chemically induced extended pluripotent cell (ciEPSC). ciEPSC are identified as an extended pluripotent cell based on properties including: (i) morphologically and (ii) functionally for example, based on their ability contribute to both TE and ICM, in vivo. The ciEPSCs can be cultured or induced to differentiate into cells of a desired type, and used in a number of applications, including but not limited to cell therapy and tissue engineering.
在体外培养后,延长分离的多能干细胞在体内产生胚外系的能力的因素,这里称为多能性化学延长剂(CEP)。延长多能细胞生成胚胎和胚外系能力的方法。将待重编程的细胞与有效量的 CEPs 接触足够长的时间,以将细胞重编程为化学诱导的扩展多能性细胞(ciEPSC)。ciEPSC 可根据以下特性确定为扩展多能性细胞:(i) 形态学上;(ii) 功能上,例如,根据它们在体内对 TE 和 ICM 的贡献能力。ciEPSCs 可培养或诱导分化为所需类型的细胞,并可用于多种应用,包括但不限于细胞疗法和组织工程。
