Mesenchymal stem cells (MSCs) are an attractive cell source for regenerative medicine as they can be easily isolated from bone marrow (BM) aspirates and expanded in culture while maintaining their ‘stemness’. In addition to differentiating into mesodermal cells, MSCs have shown considerable plasticity and generate ectodermal neurons and glia, which can be used to replace cells damaged by neurological diseases and injuries. These unique stem cells also exhibit immunomodulatory functions and secrete a variety of trophic factors which support regeneration and repair. This review focuses on the therapeutic usage of MSCs for neurodegenerative diseases and traumatic injuries to the nervous system. Animal studies demonstrate great promise for MSC transplantation in neurological disorders. In fact, a few clinical trials have already been initiated and show that MSCs are a safe cellular therapy and have great potential to become a viable treatment for neural disorders in the years to come.
