Description
Hematopoietic stem cells (HSCs) inhabit distinct microenvironments within the adult bone marrow (BM) that govern the delicate balance between HSC quiescence, self-renewal, and differentiation. It has been suggested that quiescent HSCs localize adjacent to BM arteriole endothelial cells in a significant and non-random distribution. This data suggests that the arteriole BM vascular niche may be the primary HSC niche. Because the BM arteriole niche is composed of tightly-associated pericytes, including smooth muscle actin+, LepR+, Nestin+, NG2+, and nonmyelinating Schwann cells, we sought to begin to uncouple the arteriole BM EC niche by examining its capacity to support the maintenance and expansion of HSCs ex vivo and in vivo. We developed a method to isolate and culture BM arteriole endothelial cells in serum-/growth factor-free conditions, allowing for a non-biased approach to examining their instructive function. Utilizing our protocol, we demonstrate that BM endothelial cells, but not BM stromal cells, have the capacity to expand long-term repopulating, multi-lineage HSCs in lieu of complex serum and cytokine supplementation. In addition, transplantation of arteriole endothelial cells promoted rapid hematopoietic recovery and protected HSCs following an LD50 dose of myeloablative irradiation. These data demonstrate that arteriole-derived BM endothelial cells are endowed with the necessary signals to support the self-renewal and regenerative capacity of LT-HSCs and that transplantation of arteriole BM endothelial cells could be used as a therapeutic means to decrease pancytopenias associated with myeloablative treatments to treat a wide array of disease states. Overall design: Transcriptome sequencing of bone marrow endothelial cells and bone marrow stroma, in vitro and in vivo, with and without HSC co-culture.

Description
Developmental pathways that orchestrate the fleeting transition of endothelial cells into haematopoietic stem cells remain undefined. Here we demonstrate a tractable approach for fully reprogramming adult mouse endothelial cells to haematopoietic stem cells (rEC-HSCs) through transient expression of the transcription-factor-encoding genes Fosb, Gfi1, Runx1, and Spi1 (collectively denoted hereafter as FGRS) and vascular-niche-derived angiocrine factors. The induction phase (days 0-8) of conversion is initiated by expression of FGRS in mature endothelial cells, which results in endogenous Runx1 expression. During the specification phase (days 8-20), RUNX1+ FGRS-transduced endothelial cells commit to a haematopoietic fate, yielding rEC-HSCs that no longer require FGRS expression. The vascular niche drives a robust self-renewal and expansion phase of rEC-HSCs (days 20-28). rEC-HSCs have a transcriptome and long-term self-renewal capacity similar to those of adult haematopoietic stem cells, and can be used for clonal engraftment and serial primary and secondary multi-lineage reconstitution, including antigen-dependent adaptive immune function. Inhibition of TGF? and CXCR7 or activation of BMP and CXCR4 signalling enhanced generation of rEC-HSCs. Pluripotency-independent conversion of endothelial cells into autologous authentic engraftable haematopoietic stem cells could aid treatment of haematological disorders.

Description
Atopic dermatitis (AD) is a common inflammatory skin disease with underlying defects in epidermal function and immune responses. The goal of this study was to investigate differences in gene expression in lesional skin from patients with mild extrinsic or intrinsic AD compared to skin from healthy controls and from lesional psoriasis skin. The aim was to identify differentially expressed genes involved in skin barrier formation and inflammation, and to compare our results with those reported for patients with moderate and severe AD.

To try to identify the mechanism of STAT3s indirect action we have used a genomic approach to map the binding sites of STAT3 within the genome and also used RNA-seq technology to map the changes in RNA expression and transcript isoform abundance in response to IL-10. Overall design: Examination of transcriptome changes in peritoneal macrophages when treated with IL-10 for 4 hours. RNA was extracted and sequenced.

Description
Purpose: To identify transcriptional changes by RNA-seq in tumor samples, before bevacizumab combination treatment and after bevacizumab combination treatment in both responding and non-responding recurrent glioblastoma patients Overall design: Three comparison analyses were further performed: 1.) Paired analysis of pre- and post-treated samples from responding patients; 2.) Comparison of pre-treated samples of responders vs. non-responders; 3.) Paired analysis of pre- and post-treated samples from non-responding patients The sample ''characteristics: batch'' represents a combination of the RNA-extraction date and the library-preparation date for each sample.
