The present invention chiefly aims to provide a process for directly inducing cardiomyocytes from somatic cells without performing artificial gene transfer, a cardiomyocyte obtained thereby, and a composition comprising a combination of chemical compounds capable of using for the said process. The present invention can include a process for producing a cardiomyocyte by inducing differentiation directly from a somatic cell, the process comprising a step of culturing the somatic cell in the presence of a MEK inhibitor and a cAMP inducer, and a cardiomyocyte obtained thereby, and then a composition for producing a cardiomyocyte by inducing differentiation directly from a somatic cell, the composition comprising a MEK inhibitor and a cAMP inducer. The cardiomyocytes obtained according to the present invention are useful in regenerative medicine and the like.
本发明的主要目的是提供一种在不进行人工
基因转移的情况下直接从体细胞诱导心肌细胞的工艺、由此获得的心肌细胞以及由能够用于上述工艺的化合物组合而成的组合物。本发明可包括通过直接从体细胞诱导分化产生心肌细胞的工艺,该工艺包括在
MEK 抑制剂和 c
AMP 诱导剂存在下培养体细胞的步骤,以及由此获得的心肌细胞,然后是通过直接从体细胞诱导分化产生心肌细胞的组合物,该组合物包括
MEK 抑制剂和 c
AMP 诱导剂。根据本发明获得的心肌细胞可用于再生医学等领域。
