誘導性組換えＲＮＡ因子を用いた腫瘍のない多能性胚性幹様細胞の生成

摘要

The present invention generally relates to a method for developing, generating and selecting tumor-free embryonic stem (ES)-like pluripotent cells using electroporation delivery of an inducible tumor suppressor mir-302 agent into mammalian cells. More particularly, the present invention relates to a method and composition for generating a Tet-On/Off recombinant transgene capable of expressing a manually re-designed mir-302 microRNA (miRNA)/shRNA agent under the control of doxycyclin (Dox) in human somatic/cancer cells and thus inducing certain specific gene silencing effects on the differentiation-associated genes and oncogenes of the cells, resulting in reprogramming the cells into an ES-like pluripotent state.
