Abstract
This study was performed to investigate whether colorectal cancers produce proliferative factors for venous endothelial cells, and whether the proliferative activity is related to basic FGF and VEGF and also to the clinicopathological findings. Surgically resected specimens of 17 colorectal cancer patients were fragmented and cultured, and the supernatant was collected. A human umbilical endothelial cell line (EA-hy 926 cells) was incubated with the supernatant. The proliferative activity was examined and the levels of basic FGF and VEGF were measured. The activities were found to be significantly related to VEGF, the depth of tumor invasion and the tumor stage.
