ABSTRACT
This paper is aimed to isolate and to cultivate human adipose-derived stem cells (hADSCs) from the adipose tissue by a combination of collagenase digestion, adherence to flasks and monoclonal cultural method so as to observe the morphological characteristics of the hADSCs. The immunophenotypes of hADSCs were detected by flow cytometry techniques. The general morphological characteristics of hADSCs were observed by cytochemical and immunofluorescent techniques. The ultrastructure of hADSCs was observed by transmission electron microscopy (TEM). The experimental results showed that hADSCs had unique immunophenotypes and they were positive for CD29, CD44, CD90, CD105 and CD166, but negative for CD31, CD45 and HLA-DR. Cytochemistry showed that cytoplasm of hADSCs was stained with light blue by hematoxylin-eosin, negative for Oil red O and AKP, and positive for immunofluorescence CD29 and CD166. There were abundant organella and microvilli in the ultrastructure of hADSCs. The results validate that they will offer a morphological foundation for application of the hADSCs.
