ABSTRACT: Human placental decidua basalis-derived mesenchymal stem cells (DBMSCs) have been identified as valuable sources for cell transplantation. In this study, we found that DBMSCs could be induced to form neural stem cells in the form of neurospheres. These neurospheres were further differentiated into dopamine neuron-like cells with a cocktail of cytokines. The differentiated DBMSCs were verified through the presence of a neuron-like morphology, the expression of specific dopamine neuron makers, and the production of dopamine. In addition, this differentiation capacity of DBMSCs was not affected by long-term culture, and the cells maintained a normal karyotype in vitro. The dopamine neuronal differentiation and the relative safety transplantation potential of DBMSCs may facilitate stem cell therapeutic approaches to Parkinson's disease.
