In this study, rhesus adipose stem cells were infected with recombinant adenovirus carrying the Lmxla gene and co-cultured with embryonic rat neural stem cells. Cell differentiation was induced using sonic hedgehog and fibroblast growth factor-8. Immunofluorescence staining showed that cells were positive for neuron-specific enolase and ^-tubulin II1. Reverse transcription-PCR results demonstrated that rhesus adipose stem cells were not only positive for neuron-specific enolase and I^-tubulin III, but also positive for the dopaminergic neuron marker, tyrosine hydroxylase, neurofilament, glial cell line-derived neurotrophic factor family receptor a2 and nuclear receptor related factor 1. The number of Lmxla gene-infected cells expressing the dopaminergic neuron marker was substantially greater than the number of cells not infected with Lmxla gene. These results suggest that Lmxla-mediated regulation combined with the strategy of co-culture with neural stem cells can robustly promote the differentiation of rhesus adipose stem cells into dopaminergic neurons.展开更多
