Several studies have demonstrated the differentiation of human adipose tissue-derived stem cells (hADSCs) to neuronal and glial phenotypes, but directing the fate of these cells toward dopaminergic neurons has not been frequently reported. The aim of this study was to investigate dopaminergic specification of hADSCs in vitro. ADSCs were isolated from subcutaneous abdominal adipose tissue and were characterized. For dopaminergic differentiation, a cocktail of sonic hedgehog, fibroblast growth factor 8, basic fibroblast growth factor, and brain-derived neurotrophic factor were used under a low serum condition. As the control group, the ADSCs were cultured under the same low serum condition without the dopaminergic cocktail. At the end of differentiation period, the cells expressed neuron-specific markers, NES, NSE, and NEFL, and dopaminergic markers, EN1, NURR1, PITX3, VMAT2, TH, and GIRK2 genes. TH, NURR1, and EN1 mRNAs were upregulated in the dopaminergic group compared with the control group. NEFL and TH proteins were also expressed in the differentiated cells. A total of 27.9 of the cells differentiated in dopaminergic induction medium showed positive staining for TH protein. Based on reversed-phase high-performance liquid chromatography analysis, the differentiated cells released a significant amount of dopamine in response to KCl-induced depolarization. In conclusion, results of this study indicate that hADSCs can be induced by a growth factor cocktail to produce dopamine secreting cells with possible applications for future cell replacement therapy of Parkinson's disease. © Copyright 2018, Mary Ann Liebert, Inc. 2018.
