Abstract:
OBJECTIVETo construct an eukaryotic expression vector for vascular endothelial growth factor (VEGF) 165 gene and obtain VEGF expression in rat bladder smooth muscle cells.
METHODSVEGF165 cDNA was cloned into the eukaryotic expression vector pcDNA3.1(-), and the resultant recombinant vector pcDNA3.1(-)/VEGF165 was transfected into the rat bladder smooth muscle cells by electroporation. VEGF expression in the cells was determined by RT-PCR and immunofluoresence assay, and the biological activity of VEGF in the supernant of the transinfected cell culture was tested by MTT assay.
RESULTS AND CONCLUSIONVEGF expression was obtained in the transinfected cells, and the supernant of the transinfected cell cultures stimulated the proliferation of the endothelial cells.
