Intravaginal administration of an anti-angiogenic agent, fumagillin, during blastocyst implantation inhibits pregnancy establishment in a dose-related manner in the rhesus monkey. In the present study, mated female rhesus monkeys were vaginally inserted with tampons containing vehicle (group 1; n = 5) and test agent (fumagillin, 4 mg/animal; group 2; n = 6) on cycle day 20, and endometrial tissue samples were collected on cycle day 24 from all monkeys and processed for histological examination and immunohistochemical localization for LIF, IL-6, TGF-beta and VEGF. Concentrations of estradiol-17 beta, progesterone and chorionic gonadotrophin in peripheral circulation were determined. From the serum profiles of the hormones, 2 monkeys in group 1, and 1 monkey in group 2 appeared pregnant. However, endometrial morphology revealed histological evidence of pregnancy in 3 out of 6 fumagillin-treated animals. Histometric analysis of immunohistochemical staining in epithelial, stromal and vascular compartments revealed that per cent areas occupied by immunoprecipitate for the cytokines studies did not change in epithelial and stromal compartments, except that for TGF-beta which was higher (P < 0.05) in epithelial compartment in group 2. No change was observed in immunoprecipitation areas for IL-6 in epithelial, stromal and vascular compartments. On the other hand, changes (P < 0.05) for LIF, TGF-beta and VEGF were evident in the vascular compartment. It is possible that disparate responses observed in glandular, stromal and vascular compartments in implantation stage endometrium following fumagillin treatment actually caused from associated decline in progesterone concentration in peripheral circulation. It is also possible that fumagillin, an angiostatic agent, affects the synthesis and secretion of cytokines primarily in the vascular compartment of implantation stage endometrium, and thereby manifests differential responses in epithelial, stromal and vascular compartments.
