| Research Abstract |
It is required for the improvement and process of establishment efficiency induced pluripotent stem (iPS) cells. Reprogramming of the cells involves an intermediate mesenchymal-epithelial transition (MET)-like process that is also regulated by TGF ss In this study, we have tried to find out the molecularmechanisms in MET process regulated by TGF-ss. We used mouse embryonic fibroblast (MEF) cells from TGF-b receptors conditional knockout mice crossing with CAG-Cre Tg mice. Then we generated iPS cellsfrom the MEF cells by lentivirus vectors which encode Nakayama factors under the control of doxycycline dependent expression system. These iPS cells showed clonal variety and required longer passage for stabilization.
