Oligodendrocyte precursor cells (OPCs) are considered as the main cell source for myelination in the central nervous system. Following demyelination, proliferation, migration, and differentiation capability of endogenous OPCs remarkably increase leading to remyelination in damaged areas. Despite the beneficial impacts of resident OPCs for myelin repair, the capacity of endogenous repair is low and insufficient. Therefore, several strategies have been developed to improve endogenous myelin repair. Although stem cell therapy has been introduced as a promising strategy for neurodegenerative disorders, but several limitations such as cell rejection, teratoma formation, and ethical concerns have hampered the extensive application of stem cells in clinic. In recent years, direct conversion of fully differentiated somatic cells into desired cells in the lesion area has opened a new era in regenerative medicine. In addition to direct reprogramming of somatic cells to neurons, recent evidence have also demonstrated that somatic cells, including fibroblasts and astrocytes, can be directly reprogrammed to OPC‐like cells by overexpression of some specific transcription factors, microRNAs, or application of small molecules. Interestingly, induced OPCs differentiated to myelinating oligodendrocytes that could effectively ensheath the host axons. In the present review article, the current advancements in direct conversion of somatic cells towards oligodendroglial cells have been discussed both in vitro and in vivo. [ABSTRACT FROM AUTHOR]
