Neural stem cells (NSCs) can be isolated from nervous tissues or derived from embryonic stem cells. However, their procurement for clinical applications is limited, and there is a need for alternative types of cell that have NSCs properties. In the present study, the differentiation potential of rat adipose-derived stem cells (ADSCs) was evaluated by infecting these cells with a lentiviral vector-encoding green fluorescent protein (GFP). ADSCs transduced with lentivirus were able to generate NSC-like cells, without any effects on their growth, phenotype, and normal differentiation potential. NSC-like cells derived from ADSCs formed neurospheres and expressed high levels of the neural progenitor marker nestin. In the absence of selected growth factors, these neurospheres differentiated into neurons expressing NeuN and MAP2 and GFAP-expressing glia, as determined by immunocytochemistry, Western blotting, and quantitative real-time polymerase chain reaction. These results demonstrate that ADSCs can be induced to generate neurospheres that have NSC-like properties and may thus constitute a potential source of cells in stem cell therapy for neurological disorders.
