The double FITC-UEA-I and Dil-ac-LDL fluorescence staining displayed differentiated EPCs. The expression of VEGF was found in the medium of EPCs transfected with pcDNA3hVEGF165.VEGF165 gene transfection could stimulate EPCs proliferation.

• FITC-UEA-I和DiI-ac-LDL荧光双染证实分化的EPCs,脂质体介导pcDNA3-hVEGF165质粒转染组EPCs培养基上清中表达VEGF,hVEGF165基因转染促进EPCs增殖,注射转基因EPCs的大鼠皮下局部血管增加。
