Figure 2From: Clinical application of stem cell therapy in Parkinson's disease Schematic illustration of possible sources of stem cells for therapy in Parkinson's disease. 1) Neural stem cells (NSCs) from human fetal brain, expanded and differentiated to DA-ergic neurons; 2) Pluripotent cells generated from blastocysts (ESCs) or fibroblasts (iPSCs), expanded and differentiated to DA-ergic neurons; 3) DA-ergic neurons generated by direct conversion of fibroblasts; 4) Bone marrow-derived mesenchymal stem cells (MSCs).Back to article page
