Project description:We performed RNA sequencing analyses of adult mouse bone marrow endothelial cells. Especially, we investigated gene expression profiling of endothelial cells before and after lethal irradiation or hematopoietic cell depletion. We also analyzed mouse bone marrow endothelial cell subtypes, Apln+ and diaphyseal endothelial cells. Whole bone marrow cells, lineage negative hematopoietic stem and progenitor cells, Lin- Sca1+ cKit+ cells were used as controls for the differential gene expression analyses.

Project description:This dataset was generated by RNA sequencing of bone marrow endothelial cells from femurs and tibiae of 6 day-old C57Bl/6 mice. Sample sets represent type H, type E and type L bone marrow endothelial cell subpopulations. Endothelial subpopulations are defined by their expression levels of Endomucin and CD31/Pecam1. Each dataset was generated in triplicates.

Project description:Background—Diabetes is a prevalent public health problem that affects about one third of the U.S. population and leads to serious vascular complications with increased risk for coronary artery disease. How bone marrow hematopoiesis contributes to diabetes complications is incompletely understood. We thus investigated the role of bone marrow endothelial cells in diabetic regulation of inflammatory myeloid cell production. Methods and Results—In three types of mouse diabetes, we observed enhanced proliferation of hematopoietic stem and progenitor cells (HSPC) leading to augmented circulating myeloid cell numbers. Analysis of bone marrow niche cells revealed that endothelial cells in diabetic mice expressed less Cxcl12, a retention factor promoting HSPC quiescence. Transcriptome-wide analysis of bone marrow endothelial cells demonstrated enrichment of genes involved in epithelial growth factor receptor (EGFR) signaling in mice with diet-induced diabetes. To explore whether endothelial EGFR plays a functional role in myelopoiesis, we generated mice with endothelial-specific deletion of EGFR (Cdh5Cre EGFRfl/fl). Unexpectedly, we found enhanced HSPC proliferation and increased myeloid cell production in Cdh5Cre EGFRfl/fl mice compared to wild type mice with diabetes. Disrupted EGFR signaling in endothelial cells decreased their expression of the HSPC retention factor angiopoietin-1. We tested the functional relevance of these findings for wound healing and atherosclerosis, both implicated in complications of diabetes. Inflammatory myeloid cells accumulated more in skin wounds of diabetic Cdh5Cre EGFRfl/fl mice, significantly delaying wound closure. Atherosclerosis accelerated in Cdh5Cre EGFRfl/fl mice, leading to larger and more inflamed atherosclerotic lesions in the aorta. Conclusions—In diabetes, bone marrow endothelial cells participate in the dysregulation of bone marrow hematopoiesis and promote cardiovascular complications via leukocyte overproduction. Specifically, diabetes reduces endothelial production of Cxcl12, a quiescence-promoting niche factor that reduces stem cell proliferation. We also describe a previously unknown counter-regulatory pathway, in which protective endothelial EGFR signaling curbs HSPC proliferation and myeloid cell production via angiopoietin-1.

Project description:Bone Marrow Transplantation (BMT) depends greatly on transendothelial migration of stem cells from bloodstream to bone marrow. Therefore Bone Marrow Endothelial Cells (BMECs) becomes an essential component for successful BMT. Since BMT requires prior radiation therapy therefore it is necessary to study the behaviour of BMEC in irradiated and radiprotective conditions. We have conducted transcriptome profiling of Bone Marrow Endothelial Cells (BMECs) to identify the signalling mechanisms required for transendothelial migration to bone marrow under irradiated and radioprotected conditions.
