ABSTRACT
BACKGROUND:
The rabbit adipose-derived stem cells are mostly isolated by type I col agenase digestion, but rarely by explants culture method.OBJECTIVE:
To isolate rabbit adipose-derived stem cells for adipogenic and osteogenic differentiation.METHODS:
The rabbit adipose-derived stem cells were isolated from rabbit adipose by explants culture method, and cultured in vitro fol owed by morphological observation. The grow curve and cellsurface markers CD29, CD44, CD45 of passage 3 cells were analyzed respectively by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and flow cytometry;cells from the third passages were induced for adipogenic and osteogenic differentiation by different revulsants, and cells were examined by oil red O staining and alizarin red staining . RESULTS ANDCONCLUSION:
The rabbit adipose-derived stem cells cultured in vitro exhibited a spindle-shaped appearance and could rapidly expand. Flow cytometry analysis revealed that the third passage of rabbit adipose-derived stem cells was positive for CD29, CD44, but negative for CD45. Rabbit adipose-derived stem cells were positive for oil red O staining at 14 days of adipogenic induction, and positive for alizarin red staining at 14 days of osteogenic induction. In conclusion, we could successful y isolate rabbit adipose-derived stem cells using explants culture method.
