Reciprocal communication between endometrial stromal cells and macrophages

ABSTRACT: Endometriosis is an inflammatory disease and bone marrow-derived cells are abundant in endometriotic lesions and in the peritoneal fluid of women with the disease. This study tested the hypothesis that reciprocal communication occurs between macrophages and cultured human endometrial stromal cells and that this communication contributes to the pathology of endometriosis. Changes in gene expression elicited by exposure to factors secreted by the opposing cell type were measured by DNA microarray to test this hypothesis. 716 named genes were differentially expressed in cultured endometrial stromal cells in response to factors secreted by macrophages. Genes that were up-regulated included IL8/CXCL8, MMP3, phospholamban, CYR61/CCN1, CTGF/CCN2, tenascin C, and NNMT, whereas integrin alpha 6 was down-regulated. In contrast, 15 named genes were differentially expressed in macrophages in response to factors secreted by cultured endometrial stromal cells. The data document reciprocal communication between macrophages and endometrial stromal cells and suggest that interaction with macrophages stimulates the expression of genes in endometrial stromal cells that contribute to migration, adhesion, invasion, neovascularization and mitosis of endometrial cells that may support the establishment of endometriosis.
