Relationship of the expression of transforming growth factor,vascular endothelial growth factor with angiogenesis in thyroid cancer / 中国基层医药

Objective To investigate the relationship of the expressions of transforming growth factor ?_1(TGF?_1),vascular endothelial growth factor(VEGF) with angiogenesis in thyroid cancer.Method TGF?_1,VEGF and microvessel countt(MVC) were detected by immunohistochemical method in 46 thyroid cancer specimens.Results The mean MVC was significantly higher in tumors with positive TGF?_1 or VEGF than in tumors with negtive TGF?_1 or VEGF[(26.18?4.05) vs (20.13?4.29) for TGF?_1 and (25.82?3.61) vs (19.65?6.32) for VEGF,P
