    摘要: Stem cell reprogramming genes cloned into a single sustained expression-type Sendai viral vector are shown to reprogram differentiated somatic cells into induced pluripotent stem (iPS) cells without integration of vector sequences into the host cell's genome. The genes are transduced into normal differentiated somatic cells via infection with recombinant Sendai virus. After expression of the reprogramming genes and subsequent induction of pluripotency, the vector genome RNA including the reprogramming genes is removed from the cell to establish an iPS cell that is genetically identical to the parent somatic differentiated cell thus reducing the risk of tumorigenic transformation caused by random integration of vector sequences into the host genome. The method promises to provide safe, autologous iPS cells that can be used for human cell replacement and regeneration therapeutic applications.
