The Role of microRNAs in Embryonic and Induced Pluripotency

Research on stem cells is one of the fastest growing areas of regenerative medicine that paves the way for a comprehensive solution to cell therapy. Today, stem cells are precious assets for generating different types of cells derived from either natural embryonic stem (ES) cells or induced pluripotent stem (iPS) cells. The iPS technology can revolutionize the future of clinics by offering personalized medicine, which will provide the future treatment for curing untreatable diseases. Although iPS cell therapy is now at its infancy, promising research has motivated scientists to pursue this therapeutic approach. In this article, we provide information regarding similarities and differences between ES and iPS cells, and focus on the non-integrating methods of iPS generation via RNA molecules, especially microRNAs with an emphasis on the elucidation of their role and importance in pluripotency.
