Abstract
Recent development of a synthetic mRNA-based technology for efficient reprogramming to pluripotency and cell fate conversion without any modification to the genome has generated great interest among researchers and clinicians alike. It is hoped that this technology could contribute to unmet needs on several fronts of regenerative medicine, including mechanistic study of reprogramming, generation of safe induced pluripotent stem cells suitable for clinical applications, and derivation of desired cell types for cell-replacement therapy. We will discuss the technological advancements made by this synthetic mRNA methodology, its implications, as well as the challenges that lie ahead in the field of regenerative medicine.
