Abstract:
Objective To establish the nude mouse model for in vivo research on endometriosis.So to study the mechanism and effect of anti-vascular endothelial growth factor(VEGF) antibody treatment on the growth of established endometriotic-like lesions in the nude mouse model.Methods Human endometrium is implanted into nude mice and used to test the effect of anti-VEGF antibody.The models were seperated into control groups and experimental groups(using anti-VEGF antibody).The TUNEL,PCNA and MVD were used to evaluate the effects of apoptosis,proliferation and angiogenesis.Results The explants in the control groups develop a rich blood supply that enables them to survive and grow than those in the experimental groups.The apoptosis in experimental groups was significantly higher than those of the control groups.The proliferation didn't show difference in these groups.The MVD in the control groups(human non-endometriosis 12.80?4.60,endometriosis 13.15?5.66;mouse non-endometriosis 29.7?19.6,endometriosis 34.6?16.3) were higher than those in the experimental groups(human non-endometriosis 7.17?2.25;endometriosis 7.32?1.30;mouse non-endometriosis 11.2?6.2;endometriosis 15.6?6.8).Conclusion Anti-VEGF antibody effectively interfered with the maintenance and growth of endometriotic-like lesions by disrupting the vascular supply.The anti-VEGF antibody may be provided a novel therapeutic approach for the treatment of endometriosis.
