Project description:VSMCs were cultured on Jag1 or IgG-coated plates as described above. RNA was extracted using RNA isolation kit (Qiagen). Reverse-transcription PCR was done with RNA-to-cDNA kit (Applied Biosystems). cDNA was run on a TaqMan Low-Density Array, human angiogenesis panel (Applied Biosystems , Cat#4378725), amplified on a 7900 HT Fast Real Time PCR system (Applied Biosystems) according to manufacturer’s instructions. Angiogenesis gene expression was screened for human aortic vascular smooth muscle cells that were plated for 18 hours on either Notch ligands (Jag1 or Jag2) as compared to appropriate IgG controls (IgG1 or IgG2).

Project description:The components of the exosomes are essential to understand how vascular smooth muscle cells (VSMC) and endothelial cells communicate with each other. Exosomes secreted by human VSMCs were harvested and analyzed by nanoLC-MS/MS. The activity of the identified proteins were further assessed by the in vivo matrigel plug angiogenesis assay.

Project description:Notch signaling is an evolutionarily conserved pathway that functions via direct cell-cell contact. The Notch ligand Jagged1 (Jag1) has been extensively studied in vascular development, particularly for its role in smooth muscle cell maturation. Endothelial cell-expressed Jag1 is essential for blood vessel formation by signaling to nascent vascular smooth muscle cells and promoting their differentiation. Given the established importance of Jag1 in endothelial cell/smooth muscle crosstalk during development, we sought to determine the extent of this communication in the adult vasculature for blood vessel function and homeostasis.

Project description:Platelet-derived growth factor (PDGF) signalling and the subsequent activation of the calcium ion channel, ORAI1 are critical drivers of pathological remodelling of native vascular smooth muscle cells to proliferative state, which is a process associated with various vascular diseases. This study aims to reveal transcriptional networks altered following ORAI1 inhibition in vascular smooth muscle cells. To study the effect of ORAI1 inhibition on VSMC biology, we performed RNA-Seq analysis of PDGF-stimulated primary human aortic smooth muscle cells treated with either ORAI1 inhibitor, (n=4) or with vehicle (n=4), and investigated the effect of ORAI1 inhibition on the transcriptional response of cells.

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.

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. We analyzed 3-4 replicates of the thoracic and abdominal aorta, which were previously exposed to either high-phosphate diet (HPD) or standard chow diet (SCD), respectively.

Project description: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. 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.
