    摘要： Certain embodiments disclosed herein are directed to a method of producing endoderm cells, such as definitive endoderm cells by exposing stem cells such as embryonic stem cells or induced pluripotent stem (iPS) cells to an effective amount of at least one compound described herein to differentiate the stem cells into the endoderm cells such as definitive endoderm cells. Differentated endoderm cells produced by the methods disclosed herein can be differentiated into pancreatic epithelium, and other endoderm derivatives such as thymus, liver, stomach, intestine and lung. Another aspect of the present invention relates to a method of producing pancreatic progenitor cells, such as Pdx1-positive pancreatic progenitor cells by exposing endoderm cells, such as definitive endoderm cells to an effective amount of at least one compound described herein to differentiate the definitive endoderm cells into Pdx1-positive pancreatic progenitor cells. Kits and compositions comprising Pdx1-positive pancreatic progenitor produced using the methods are also described.

    摘要翻译： 本文公开的某些实施例涉及通过将干细胞如胚胎干细胞或诱导的多能干（iPS）细胞暴露于有效量的本文所述的至少一种化合物来分化本发明的内胚层细胞，例如定形内胚层细胞， 干细胞进入内胚层细胞，如定形内胚层细胞。 通过本文公开的方法产生的分化的内胚层细胞可以分化成胰腺上皮和其它内胚层衍生物如胸腺，肝，胃，肠和肺。 本发明的另一方面涉及通过将内胚层细胞如定形内胚层细胞暴露于有效量的至少一种本文所述的化合物来分化定形内胚层来产生胰腺祖细胞如Pdx1阳性胰腺祖细胞的方法 细胞进入Pdx1阳性胰腺祖细胞。 还描述了使用该方法制备的包含Pdx1阳性胰腺祖细胞的组合物和组合物。
