The Effects of Hedgehog Ligand Neutralising Antibody 5E1 in a Mouse Model of Endometriosis

Abstract

Objective: Endometriosis is a common and painful condition characterized by the formation of endometrial lesions within the peritoneal cavity. Previous studies have suggested a role for hedgehog signalling in the pathogenesis of endometriosis. We investigated the role of hedgehog signalling in the establishment of endometriosis lesions using 5E1, a hedgehog ligand neutralising antibody, and a mouse model of endometriosis. Results: Treatment with 5E1, reduced the number of lesions found on the mesentery. No significant changes were found in the size of lesions, abundance of endometrial epithelial cells, proliferation or apoptosis in the lesions.
