摘要: The human carcinoma HEp3 grows on the chorioallantoic membrane and metastasizes to chicken embryo with kinetics that are quantitatively predictable. We have used this experimental system test whether plasminogen activator produced by tumor is required for metastasis. Rabbit antibodies were raised against urinary urokinase; these cross-reacted blocked catalytic activity of HEp3-PA but did not inhibit PA. When administered intravenously embryos had received an inoculum cells, anti-urokinase growth at site primary inoculation membrane, they either prevented or strongly inhibited metastasis lung. Antibody treatment delayed onset pulmonary metastasis, indicating during early stages process.
