ABSTRACT
BACKGROUND:
The decel ularized porcine smal intestinal submucosa is a kind of bioactive extracel ular matrix, which is mainly composed of col agen, glycoprotein, proteoglycan and rich in col agen, glycosaminoglycan and various growth factors, and these components play an important role in promoting the differentiation and proliferation of tissue cel s.OBJECTIVE:
To prepare the injectable smal intestinal submucosa and to investigate its co-culture with rat adipose-derived mesenchymal stem cel s in vitro.METHODS:
The injectable smal intestinal submucosa and rat adipose-derived stem cel s were prepared. Cel counting kit-8 test for cel proliferationPassage 3 adipose-derived stem cel s were seeded onto the injectable smal intestinal submucosa (experimental group) and cel s cultured under normal condition as control group. The cel proliferation was observed at 1, 3, 5 and 7 days of incubation. Live/dead staining test for the survival of cel sPassage 3 adipose-derived stem cel s were respectively cultured in the injectable smal intestinal submucosa extracts (experimental group) and complete culture medium (control group). Cel survival was determined at 1, 3, 5 and 7 days of culture. RESULTS ANDCONCLUSION:
Scanning electron microscope oval and strip adipose-derived stem cel s adhered onto the material. The absorbance values in the experimental group were higher than those in the control group at 1 and 5 days of incubation (P<0.05). Cel survivalThe number of cel s appeared to be in a rising trend with time in both two groups;after 1-day co-culture, al cel s in the two groups survived. Then dead cel s appeared in both two groups, showing no significant difference. These results show that the injectable smal intestinal submucosa exhibits a good cytocompatibility.
