Neurodegenerative and neuroimmune diseases, such as multiple sclerosis (MS), Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS) share a common pathologic hallmark i.e. loss of neurons in the central nervous system (CNS), despite diverse pathological manifestations. These diseases present major challenges to global health due to incurable or extremely difficult to treat, imposing a heavy burden on society and families. Stem cell therapy, as a novel promising approach for treating various neurological diseases, harnesses the regenerative potential of stem cells to repair damaged neural tissues and circuits, and has become the only hope for patients to recover their health or delay the deterioration of disease symptoms. In recent years, researchers have successfully generated neurons from multiple types of stem cells, and good curative effects have been achieved in their animal models and in clinical trials. This comprehensive review elaborates on the relevant content of stem cell biology, focuses on conducting an in-depth analysis of the current application status of various stem cells in major neurodegenerative and neuroimmune diseases including MS, AD, PD and ALS, kindling the hope for the development of stem cell-based cell therapies in neurological diseases.
