摘要
Recent research has shown that defined sets of exogenous factors are sufficient to convert rodent and human somatic cells directly into induced neural stem cells or neural precursor cells（iNSCs/iNPCs）.The process of transdifferentiation bypasses the step of a pluripotent state and reduces the risk of tumorigenesis and genetic instability while retaining the self-renewing capacity.This iNSC/iNPC technology has fueled much excitement in regenerative medicine,as these cells can be differentiated into target cells for replacement therapy for neurodegenerative diseases.Patients＇ somatic cell-derived iNSCs/iNPCs have also been proposed to serve as disease models with potential value in both fundamental studies and clinical applications.This review focuses on the mechanisms,techniques,and applications of iNSCs/iNPCs from a series of related studies,as well as further efforts in designing novel strategies using iNSC/iNPC technology and its potential applications in neurodegenerative diseases.
