Research Abstract

Previously c-Myc is thought to be one of the risks for tumorigenicity of iPS-derived chimera mice. To overcome this problem, we found that c-Myc can be replaced with L-Myc. From detailed study, a strong transforming activity of c-Myc negatively acted in the early establishment of iPS cells. On the other hand, little transforming activity of L-Myc efficiently inhibited the expression of a gene highly expressed in fibroblasts resulted in promotion of the establishment of iPS cells.
