ABSTRACT
<p><b>OBJECTIVE</b>To investigate the possibility of adipose-derived stromal cells (ADSCs) transfeced by adenovirus containing human bone morphogenetic protein-2 (Ad-hBMP-2) gene and their osteogenic potential.</p><p><b>METHODS</b>ADSCs were obtained from inguinal fat tissue of 4 weeks old SD rats. After exposure to adenovirus containing green fluorescent protein(Ad-GFP), fluorescent microscope was used to observe gene transfection effect once 12 hours. After transfected with Ad-hBMP-2, cytochemistry, immmucytochemistry and Western blot were used to examine the expression of alkaline phosphatase (ALP), osteocalcin (OC) and hBMP-2.</p><p><b>RESULTS</b>After exposed to Ad-GFP 12 hours, 52% ADSCs were observed being transfected and 48 hours later reached 95%. The double number time belonged after transfecting with Ad-hBMP-2, and cytochemistry, immucytochemistry and Western blot examines indicated positive results of ALP, OC, hBMP-2 after 48 hours.</p><p><b>CONCLUSION</b>Adipose tissue contains abundant ADSCs which could be transfected as gene vectors by adenovirus, ADSCs transfected with Ad-hBMP-2 can convert to ostoeblasts, and can act as a kind of seed cells for osteo-tissue engineering.</p>
