They are evenly distributed throughout the gray and white matter and continue to proliferate and generate new oligodendrocytes (OLs) throughout life. They were understudied until a few decades ago when immunolabeling for NG2 and platelet-derived growth factor receptor alpha revealed cells that are distinct from mature OLs, astrocytes, neurons, and microglia. In this review, we provide a summary of the known properties of OPCs with some historical background, followed by highlights from recent studies that suggest new roles for OPCs in certain pathological conditions.}, year = {2021}, journal = {Neurophathology }, volume = {41}, chapter = {161-173}, pages = {161-173}, month = {06/2021}, url = {https://onlinelibrary.wiley.com/doi/10.1111/neup.12732}, }
