[Induced pluripotent stem cell technology and its application in disease research]

Since Takahashi and Yamanaka reported the generation of induced pluripotent stem cells (iPSCs) in 2006, the field of pluripotent stem cells has entered an unprecedented state of development. It plays an important role in disease modeling, drug discovery and cell therapy, and promotes the development of cell biology and regenerative medicine. At present, iPSC technology has become an important tool for studying of pathological mechanisms. New drugs screened by iPSC technology are being developed, and the number of clinical trials using iPSC-derived cells is gradually increasing. The latest research progress of iPSCs, combined with gene editing technology and 3D organoid methodology, promotes the further applications of iPSCs in disease research. In this review, we introduce the innovation of reprogramming methods in recent years, analyze the advantages and disadvantages of four reprogramming methods: integrated virus vector system, integrated non-viral vector system, non-integrated virus vector system and non-integrated non virus vector system. At the same time, we summarize the latest research progress on iPSCs in disease modeling and clinical treatment strategies, so as to provide a reference for further in-depth research in various fields of iPSCs.
