ABSTRACT

Objective To investigate the feasibility of genetically modified X-linked inhibitor of apoptosis protein (XIAP) of rat adipose-derived mesenchymal stem cells (ADSCs) by isolating and cultivating rat ADSCs in vitro. Methods ADSCs were isolated from rat groin fat pads by collagenaseⅠdigestion under sterile condition. ADSCs were passaged and amplified with 10%FBS DMEM. The multi-differentiation potential of ADSCs was verified by cultivated with differentiation medium. XIAP expression plasmid was transfected into ADSCs. The anti-apoptotic ability of XIAP transduction was detect-ed by Western blotting assay. Results ADSCs were mainly spindle-shaped and whirlpool-shaped arranged. Results of flow cytometry showed that there were higher expressions of CD29, CD44, CD90 and CD105 in ADSCs, which differentiated into lipocytes, chondrocytes and osteoblasts under specific conditions. There is XIAP gene modified adipose-derived mesenchy-mal stem cells Band in the corresponding molecular mass of PVDF membrane area. Conclusion ADSCs were isolated from rat subcutaneous fat pads and were easily cultivated, passaged and amplified. ADSCs can differentiate into osteoblasts, chon-drocytes and adipocytes under specific conditions, which are better resource for being used in cell therapy and tissue engi-neering.
