Objective To study the role of the balance between thrombospondin-1 (TSP-1) and vascular endothelial growth factor (VEGF) in the neovascularization of hepatocellular carcinoma (HCC).
AIM: To establish the mutant of coding calcium binding fragment of the 13th exon of human thrombospondin-1 (TSP-1) gene with polymerase chain reaction (PCR) site directed mutagenesis technology.
