Project description:Reciprocal communication between endometrial stromal cells and macrophages
| PRJNA122051 | ENA
Project description:Immune system cells and cells of the endometrium have long been proposed to interact in both physiological and pathological processes. The current study was undertaken to examine communication between cultured monocytes and endometrial stromal cells and also to assess responses of endometrial stromal cells to treatment with estradiol (E) in the absence and presence of medroxyprogesterone acetate (P). A telomerase-immortalized human endometrial stromal cell line (T-HESC) and the U-937 monocyte cell line were used. T-HESC were treated with E ± P ± monocyte conditioned medium; U-937 were treated ± T-HESC conditioned medium. Gene expression in response to treatment was examined by DNA microarray. Bi-directional communication, as demonstrated by changes in gene expression, clearly occurred between U-937 monocytes and T-HESC endometrial stromal cells.

Project description:In this study, we characterize the fusion protein produced by the EPC1-PHF1 translocation in Low Grade Endometrial Stromal Sarcoma (LG-ESS) and Ossifying FibroMyxoid Tumors (OFMT). We express the fusion protein and necessary controls in K562 Cells. The fusion protein assembles a mega-complex harboring both NuA4/TIP60 and PRC2 subunits and enzymatic activities and leads to mislocalization of chromatin marks in the genome, linked to aberrant gene expression.

Project description:Interactions between developing B-lymphocytes and stromal cells reveal complex interactions and two-way communication

Project description: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.

Project description:A population of endometrial cells displaying key properties of mesenchymal stem cells (eMSC) has been identified in human endometrium. eMSC co-express CD146 and PDGFRB surface markers, have a perivascular location, and likely represent the reservoir of progenitors giving rise to the endometrial stromal fibroblast lineage. Endometrial stromal cells isolated from 16 oocyte donors and 3 benign gynecologic surgery subjects were FACS sorted into four populations: CD146+/PDGFRB+ (eMSC); CD146+/PDGFRB- (endothelial cells); CD146-/PDGFRB+ (stromal fibroblasts); CD146-/PDGFRB- (mixed population) then subjected to gene expression analysis on Affymetrix Human Gene 1.0 ST arrays, and differentially expressed genes compared between eMSC, stromal fibroblast, and endothelial cell populations. Ninety-two genes were validated by multiplex quantitative RT-PCR on seventy of these sorted cell populations. Immunohistochemistry was used to verify the perivascular location of eMSCs.Principal component analysis and hierarchical clustering showed eMSC clustering discretely near stromal fibroblasts and separately from endothelial cells. eMSC expressed pericyte markers and genes involved hypoxia response, inflammation, proteolysis, and angiogenesis/vasculogenesis – all relevant to endometrial tissue breakdown and regeneration. Additionally, eMSC displayed distinct gene profiles for cell-cell communication and regulation of gene expression. Overall, the phenotype of the eMSC is that of a multipotent pericyte responsive to hypoxic, proteolytic, and inflammatory stimuli, able to induce angiogenesis, migrate and differentiate into lineage cells, and potentially respond to estradiol and progesterone. Identifying the pathways and gene families described herein in the context of the endometrial niche, will be valuable in understanding normal and abnormal endometrial development in utero and differentiation in adult uterus. The multipotent, perivascular endometrial mesenchymal stem cell has a “niche phenotype” of high Notch, TGFB, IGF, and Hedgehog and low canonical/non-canonical Wnt and EGF signaling. Oocyte donors with no known uterine pathology underwent endometrial biopsy at the time of oocyte retrieval, following comparable GnHR agonist downregulated ovarian stimulation protocols. Tissue was digested and stromal cells isolated and sorted based on expression of CD146 and PDGFRB. RNA was extracted and hybridized on Affymetrix microarrays. Resulting data were compared between sorted isolated cell populations.
