Objectine To establish the isolation,cultivation and identification methods of human adipose - derived mesenchymal stem cells(hADSCs)in vitro. Methods The hADSCs were isolated from abdomen epiploica adipose tissue by collagenase digestion. Expression of cel-lular markers,the proliferative capacity,and multipotential differentiation were respectively studied with flow cytometry analysis,cell counting,Oil Red O,and Von Kossa staining. Results The isolated hADSCs all displayed typical fibroblast - like morphological features. Phenotypic studies revealed that hADSCs were positive for CD29,CD44,CD73,CD90,CD105,CD166 and negative for CD45 and HLA - DR. The growth curve and doubling time analysis revealed high capability for self - renewal and proliferation. Oil Red O and Von Kossa staining demonstrated a multipo-tent differentiation capacity of hADSCs. Conclusion The data described here suggest that an efficient isolation and cultivation method of hADSCs has been established.
