RNA-seq expression analysis to determine expression profile similarities between fibroblasts, induced endothelial cells from fibroblasts, and human dermal microvascular endothelial cells
ABSTRACT: The goal of this study was to determine the similarity between human dermal microvascular endothelial cells, induced endothelial cells from fibroblasts, and fibroblasts through RNA-seq expression analysis. RNA samples from independently induced cultures, plus fibroblast and human dermal microvascular endothelial cultures were converted into individual cDNA libraries using Illumina TruSeq methods and subjected to single-end 50 base-sequence analysis at 20-30 million read depths. Examination of one fibroblast culture, one human dermal mibrovascular endothelial cell culture, and two induced endothelial cell cultures.
Project description:Whole transcriptome comparisons of proliferating pure cultures of neonatal dermal microvacsular endothelial cells to infantile hemangioma endothelial cells. The total RNA was obtained from human dermal microvascular endothelial cells and infantile hemangioma endothelial cells. Illumina microarrays were performed to determine the whole genome expression differences between the cell lines.
Project description:Global gene expression analysis of FACS-purified CD31+CD146+ vascular progenitors (VP) derived from (a) human embryonic stem cells (VP-hESC), (b) adult fibroblast derived induced pluripotent stem cells (VP-AdF-iPSC), (c) stromal primed cord blood CD34+ myeloid progenitor derived iPSC (VP-sp-CB-iPSC), (d) corresponding starting fibroblasts and myeloid progenitors, (e) human umbilical vein endothelial cells, and (f) human dermal microvascular endothelial cells. Total RNA was harvested from (a) adult fibroblasts, (b) human myeloid progenitors: Non-nucloefected CD34+ CB cells that were expanded with growth factors from Day -3 until Day 0 and harvested, (c) FACS-purified CD31+CD146+ vascular progenitors (VP) that were differentiated from human embryonic stem cells (hESC), (d) VP differentiated from low passage stromal-primed episomal iPSC derived from growth-factor activated cord blood myeloid progenitors, (e) VP differentiated from iPSC derived from adult fibroblasts, (f) human umbilical vein endothelial cells, and (g) human dermal microvascular endothelial cells.. Illumina HumanHT-12 V4.0 expression beadchips were used for all analyses in this series. Three or independent samples of each sample type were each run on individual microarrays.
Project description:Normal human dermal fibroblasts (NHDF) and human lung microvascular endothelial cells (HMVEC-L) were irradiated with protons (0, 0.5, 1 and 2 Gy, 1GEv/n) at Brookhaven National Labs (BNL). Aim of the study is to find differentially transcribed genes in dependence of radiation dose/source and cell type.

Aim of the study is to find differentially transcribed genes in dependance of radiation dose/source and cell type.
Project description:BMP9 signaling has been implicated in hereditary hemorrhagic telangiectasia and vascular remodeling, acting via the HHT target genes, endoglin and ALK1. This study sought to identify endothelial BMP9-regulated proteins that could affect the HHT phenotype. Gene ontology analysis of cDNA microarray data obtained following BMP9 treatment of primary human endothelial cells indicated regulation of chemokine, adhesion, and inflammation pathways. The sample set is comprised of three biological replicate control human dermal microvascular endothelial cells, and three treated (5 ng/ml human recombinant BMP9) biological replicate human dermal microvascular endothelial cells

Vascular endothelium expressing endothelial nitric oxide
synthase (eNOS) produces nitric oxide (NO), which has a number
of important physiological functions in the microvasculature.
The rate of NO production by the endothelium is a critical
determinant of NO distribution in the vascular wall. We have
analyzed the biochemical pathways of NO synthesis and
formulated a model to estimate NO production by the
microvascular endothelium under physiological conditions. The
model quantifies the NO produced by eNOS based on the kinetics
of NO synthesis and the availability of eNOS and its
intracellular substrates. The predicted NO production from
microvessels was in the range of 0.005-0.1 microM/s. This range
of predicted values is in agreement with some experimental
values but is much lower than other rates previously measured
or estimated from experimental data with the help of
mathematical modeling. Paradoxical discrepancies between the
model predictions and previously reported results based on
experimental measurements of NO concentration in the vicinity
of the arteriolar wall suggest that NO can also be released
through eNOS-independent mechanisms, such as catalysis by
neuronal NOS (nNOS). We also used our model to test the
sensitivity of NO production to substrate availability, eNOS
concentration, and potential rate-limiting factors. The results
indicated that the predicted low level of NO production can be
attributed primarily to a low expression of eNOS in the
microvascular endothelial cells.
