Abstract (original English)

Mesenchymal stem cells derived from adipose tissue have the capacity to differentiate into endodermal, mesoderm and ectodermal cell lineages in vitro, which are an ideal engraft in tissue-engineered repair. In this study, mouse adipose-derived stem cells (ADSCs) were isolated from subcutaneous fat. The markers of ADSCs, CD13, CD29, CD44, CD71, CD73, CD90, CD105, CD166, Nestin, GFAP and MAP-2 were detected by immunofluorescence assays. The ADSCs were cultured in cocktail factors (including ATRA, GGF-2, bFGF, PDGF and forskolin) for neurogenic differentiation. The neurogenic cells markers, Nestin, GFAP and MAP-2 were analyzed using immunofluorescence and real-time PCR after dramatic changes in morphology. Neurogenic cells from ADSCs were autologous transplanted into the mouse of spinal cord injury for observation neurogenic cells colonization in spinal cord. The result demonstrated that the mouse ADSCs were positive for the CD13, CD29, CD44, CD71, CD73, CD90, CD105 and CD166 but negative for neurogenic cell markers, MAP-2, GFAP and Nestin. After neurogenic differentiation, the neurogenic cells were positive for neurogenic cell special markers, gene expression level showed a time-lapse increase, and the cells were successful colonized into spinal cord. In conclusion, our research shows that a population of neuronal cells can be specifically generated from ADSCs and that induced ce
