Previously, we reported that the rabbit prothrombin fragment 2 (kringle 2 domain) has an anti-endothelial cell proliferative effect. In this report, we show that not only rabbit prothrombin fragment 2 but also human prothrombin fragment 1 and 2 have an inhibitory effect on bFGF-stimulated BCE cell growth. Human prothrombin fragment 1 and 2 obtained as proteolytic fragments of human prothrombin display potent inhibitory effects on bovine capillary endothelial cells with a half-maximal concentration (ED50) of approximately 100 nM and 120 nM, respectively. As rabbit prothrombin fragment 2, the human prothrombin fragment 1 and 2 also inhibit angiogenesis in the chorioallantoic membrane (CAM) of chick embryos.
