The object of the present invention is to provide a differentiation inhibiting agent which allows culture of a stem cell or an embryonic stem cell in an undifferentiated state without use of any feeder cell, a method for culturing using the same, a cell culture liquid using the same, and a cell prepared by culturing using this differentiation inhibiting agent. The present invention provides a differentiation inhibiting agent which comprises a low molecular weight compound, especially a tetrahydroisoquinoline derivative, as an active ingredient; a method for safely culturing a stem cell in large scale in undifferentiated state in the absence of feeder cell which comprises culturing a stem cell by using a tetrahydroisoquinoline derivative; a culture liquid for stem cells comprising a tetrahydroisoquinoline derivative; and a cell which is obtained by culture using a tetrahydroisoquinoline derivative as a differentiation inhibiting agent.
本发明的目的是提供一种可在不使用任何饲养细胞的情况下培养未分化状态的干细胞或胚胎干细胞的分化抑制剂、使用该抑制剂的培养方法、使用该抑制剂的细胞培养液以及使用该分化抑制剂培养制备的细胞。本发明提供了一种由低分子量化合物,特别是四氢异喹啉衍生物作为活性成分的分化抑制剂;一种在没有饲养细胞的情况下安全地大规模培养未分化状态的干细胞的方法,该方法包括使用四氢异喹啉衍生物培养干细胞;一种含有四氢异喹啉衍生物的干细胞培养液;以及一种使用四氢异喹啉衍生物作为分化抑制剂培养得到的细胞。
