Project description:Background. Heterogeneity in vascular smooth muscle cells (VSMCs) has been classically defined with a small set of predefined markers. Single cell genomics provides a unique unbiased approach to evaluate VSMC phenotypes. Objectives. The goal of this study was to define the heterogeneity of primary murine VSMCs grown in culture. VSMCs grown in culture are routinely used as a model of VSMCs in the vessel wall. We wanted to better understand the assumptions of this model. RNA sequencing was performed on single aortic VSMCs from 3-4 month old male mice at passages 1 and 2 (P1 and P2). Single cell contractility measurements were performed using Traction Force microscopy.

Project description:Smooth muscle cells (SMCs) are important in a number of physiological systems and organs, including the cardiovascular system. The hallmark property of differentiated SMCs is the ability to contract, but contractile SMCs themselves show a range of phenotypes allowing prolonged tonic contraction in vascular smooth muscle or rapid phasic contraction in tissues such as bladder. Another distinctive characteristic, in contrast with terminally differentiated striated muscle cells, is that SMCs exhibit phenotypic plasticity. Vascular SMCs are able to modulate their phenotype along a continuum between a contractile phenotype, characteristic of healthy blood vessels, and a more proliferative âsyntheticâ phenotype, so-named for the enhanced synthesis and secretion of extracellular matrix components. Synthetic phenotype cells are found in a number of pathological situations such as atherosclerosis and arterial injury. We used mouse exon-junction (MJAY) arrays to gain insights into both the global contribution of alternative splicing events in re-shaping the transcriptome of dedifferentiating mouse aorta and bladder SMCs, and into the underlying regulatory mechanisms of the alternative splicing program. Affymetrix splice junction arrays (MJAY) were used to profile changes in both alternative splicing and transcript levels during the phenotypic modulation of smooth muscle cells when placed in culture. RNA extracted from intact aorta and bladder smooth muscle tissue was used for differentiated samples. For dedifferentiated, proliferative samples smooth muscle cells were enzymatically dispersed and grown in tissue culture for a week. Triplicate RNA samples were prepared from smooth muscle tissue of mouse aorta and bladder (differentiated) and from smooth muscle cells from each tissue cultured for 7 days (proliferative). The samples allowed comparison of alternative splicing (and other transcriptome) changes between differentiated and proliferative smooth muscle cell samples from two distinct types of smooth muscle cell, as well as allowing direct comparison of aorta (tonic smooth muscle) and bladder (phasic smooth muscle).

Project description:Rapid regeneration of smooth muscle after vascular injury is essential for maintaining proper artery function. The current view holds that pre-existing smooth muscle proliferate and expand in responding to vascular injury, contributing to virtually all new smooth muscle cells. Whether resident vascular stem cells for smooth muscle exist remains controversial and their putative functional role for artery repair and regeneration is elusive. Here we performed cell fate mapping and single cell RNA sequencing to identify Sca1+ vascular stem cells (VSCs) residing in the adventitial layer of artery wall.

Project description:We report the application of small RNA sequencing for high-throughput profiling of small RNA under 75 bp in vascular smooth muscle cell. By a reading depth of 30M and single stranded sequencing, we generated the small RNA signature on differentiated and de-differentiated vascular smooth muscle cell induced by PDGF-BB and H3K4me2 editing. We found that PDGF-BB and H3K4me2 editing induced de-differentiation modulated miRNA profile significantly, which was demonstrated at least in part responsible for modulated vascular smooth muscle cell phenotype.

Project description:Smooth muscle cells play a critical role in multiple cardiovascular diseases. Sca1+ cells are believed to be smooth muscle progenitors. However, the exact identity and the role of Sca1+ cells in vascular regeneration remains unclear.Here we performed single cell RNA sequencing to identify the mechanism underlying Sca1+ cells differentiate into smooth muscle cells.

Project description:Aims: The microcirculation serves crucial functions in adult heart, distinct from those carried out by epicardial vessels. Microvessels are governed by unique regulatory mechanisms, impairment of which leads to microvessel-specific pathology. There are few treatment options for patients with microvascular heart disease, primarily due to limited understanding of underlying pathology. We developed an integrated process for simultaneous isolation and culture of the main cell types comprising the microcirculation in adult mouse heart: endothelial cells, pericytes and vascular smooth muscle cells, and here we characterize the transcriptional profile of each cell type. Methods and Results: Confluent cultures of mouse cardiac endothelial cells, pericytes and vascular smooth muscle cells underwent transcriptional profiling using RNA sequencing. We define the top 50 transcripts expressed by each cell type. Conclusions: We define microvascular cell transcriptional profiles, identify novel transcripts, and confirm established cell-specific markers. Our results allow identification of unique markers and regulatory transcripts that govern microvascular physiology and pathology.

Project description:The prevalence of cardiovascular disease varies with sex, and the impact of intrinsic sex-based differences on vasculature is not well understood. Animal models can provide important insight into some aspects of human biology, however not all discoveries in animal systems translate well to humans. To explore the impact of chromosomal sex on proteomic phenotypes, we used iPSC-derived vascular smooth muscle cells from healthy donors of both sexes to identify sex-based proteomic differences and their possible effects on cardiovascular pathophysiology. Our analysis confirmed that differentiated cells have a proteomic profile more similar to healthy primary aortic smooth muscle than iPSCs. We also identified sex-based differences in iPSC-derived vascular smooth muscle in pathways related to ATP binding, glycogen metabolic process, and cadherin binding as well as multiple proteins relevant to cardiovascular pathophysiology and disease. Additionally, we explored the role of autosomal and sex chromosomes in protein regulation, identifying that proteins on autosomal chromosomes also show sex-based regulation that may affect the protein expression of proteins from autosomal chromosomes. This work supports the biological relevance of iPSC-derived vascular smooth muscle cells as a model for disease, and further exploration of the pathways identified here can lead to the discovery of sex-specific pharmacological targets for cardiovascular disease.

Project description:Vascular mineralization is a carefully orchestrated process, regulated by a number of promoters and inhibitors that function to ensure effective hydroxyapatite formation. Here we sought to identify new regulators of this process through a time series microarray analysis of mineralising primary vascular smooth muscle cell cultures over a 9 day culture period.
