Conversion of human fibroblasts into vascular cells (methylation)

ABSTRACT: We report a novel technique to reprogram human fibroblasts into endothelial and smooth muscle cells using partial iPSC reprogramming and chemically defined media. Using appropriate media conditions for differentiation of human pluripotent cells to CD34+ vascular progenitor cells, we show that temporary expression of pluripotent transcription factors and treatment with chemically-defined media, will induce differentiation of human fibroblasts to CD34+ vascular progenitor cells. Sorted CD34+ cells can then be directed to differentiate into vascular endothelial cells expressing a variety of smooth muscle markers.

Sorted CD34+ cells can then be directed to differentiate into vascular endothelial cells expressing a variety of smooth muscle markers. We have assessed the global DNA methylation (Illumina Infinium HD 450K DNA methylationBeadChips) and transcriptional (Illumina HT12v4 Gene Expression Bead Array) profiles of transdifferentiated endothelial cells and smooth muscle, human embryonic stem cell (hESC) and human induced pluripotent stem cell (hiPSC) differentiated CD34+ angioblasts, hESCs, hiPSC, primary smooth muscle and primary human umbilical vein endothelial cells using microarrays.

Impact of high-phosphate diet on aortic gene expression

Project description:Uremic media calcification is not only driven by systemic factors such as hyperphosphatemia, but also crticially dependent on vascular smooth muscle cells per se. We hypothesized that the different developmental origins of vscular smooth muscle cells might lead to a heterogeneous susceptibility to develop media calcification. Upon high-phosphate diet, the transcriptional profile revealed an induction of an inflammatory vascular smooth muscle phenotype only in the abdominal, but not in the thoracic aorta. Thus, smooth muscle cells from different lineages responded differently to morphogenetic cues in vivo.

Global gene expression analysis of vascular progenitors differentiated from human embryonic stem cells or induced pluripotent stem cells, corresponding donor starting cells, and mature human endothelial cells

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.

Differential gene expressions of human pluripotent stem cells derived cells in different culture system

Project description:Human pluripotent stem cells (H9s) were differentiated into endothelial cells (ECs), neural stem cells (NSCs) and vascular smooth muscle cells (VSMCs) in 2 dimentional, 3 dimensional PEG hydrogel and alginate hydrogel culture system, and we compared their differential gene expression in different culture system, respectively.

Expression data of RNA isolated from C57/BL6 mouse aortic endothelial cells (MAECs)

Project description:Our goal is to study the contribution of endothelial, smooth muscle, and macrophage gene expression to early atherosclerosis using vessels from healthy, pre-lesioned, and lesioned mice. To accomplish this, we developed a method to isolate endothelial cells directly from the aorta and quantitate transcripts in RNA isolated from these cells. We performed expression array analysis on RNA isolated directly from the vascular cells of individual control, pre-lesioned, and atherosclerotic mouse aortas. Array expression analysis was not performed on smooth muscle cells or macrophages. RNA from MAEC of pre-lesioned hyperlipidemic and normal-lipidemic mice was isolated, amplified, and arrayed. Mouse aortas were also treated in either media (DMEM) or media containing either LPS, oxLDL, or oxPAPC for 4 hours prior to RNA isolation and amplification. Only samples with a RIN of 7.0 or greater were used for analysis.
