Project description:Mural cells are central to vascular integrity and function. In this study, we demonstrate the innovative use of the transcription factor NKX3.1 to guide the differentiation of human induced pluripotent stem cells into mural progenitor cells (iMPCs). By transiently activating NKX3.1 in mesodermal intermediates, we developed a method that diverges from traditional growth factor-based differentiation techniques. This approach efficiently generates a robust iMPC population capable of maturing into diverse functional mural cell subtypes, including smooth muscle cells and pericytes. These iMPCs exhibit key mural cell functionalities such as contractility, deposition of extracellular matrix, and the ability to support endothelial cell-mediated vascular network formation in vivo.

Project description:Purpose: Pericytes, the mural cells of blood microvessels, have come into focus as regulators of microvascular development and function, but due to paucity of defining markers, the identification and functional characterization of PC remain problematic, and reported data are often controversial. Here, we used a new approach for the isolation of mural cell from mouse brain in combination with RNA-sequencing (RNA-seq) and previously published vascular transcriptome data to assemble a state-of-the-art catalogue of brain mural cell-enriched gene transcripts. Methods: We isolated double positive cells from the brain of Pdgfrb-eGFP/NG2-DsRed transgenic mice using FACS. Cells were lysed, RNA extracted and sequenced with next-generation sequencing (NGS). For comparison, we also determined the transcriptome of brain microvascular fragments (containing both endothelial cells and mural cells) isolated by mechanical tissue disintegration, collagenase digestion and immune-panning using anti-CD31 antibodies coupled to magnetic beads. The reads were aligned to the Ensembl mouse gene assembly (NCBIM37) using Tophat2 software (version 2.0.4). The duplicated reads were removed using the picard tool (version 1.92). To identify the genes significantly enriched in the pericyte samples as compared with microvascular samples, statistical tests were performed using the Cufflinks tool (version 2.2.1) Results: The result showed that mRNA transcripts representing 856 different genes were enriched more than two-fold in FACS isolated Pdgfrb-eGFP/NG2-DsRed double positive cells compared with whole microvascular fragments (False Discovery Rate < 0.05) The RNA from three FACS sorted brain mural cell samples and three whole brain microvascular samples isolated from three animals were processed and sequenced on the Illumina HiSeq 2500 platform in the sequencing facility in Uppsala University.

Project description:In the study we show that a specific peripheral glial population, derived from boundary cap (BC) cells, constitutes a major source of mural cells for the developing vasculature. Using Cre-based reporter cell tracing and single cell transcriptomics, we show that BC cell derivatives migrate along the nerves and differentiate into pericytes and vascular smooth muscle cells in the skin. The switch from glial to mural molecular identity is initiated while the cells are still associated with nerves To further characterize this transition glial to vascular identity, we performed single cell transcriptomic analyses (scRNA-seq) on FACS-purified traced cells from dissociated E12.5 skin. Tomato-positive cells were isolated by FACS from embryonic skin at E12.5. Around 10,000 cells were loaded into one channel of the Chromium system using the V3 single cell reagent kit (10X Genomics) We analyzed 2527 single cell transcriptomes with a mean number of expressed genes per cell of 4,696. This study highlights the plasticity of BC derivatives and uncovers a novel, nerve-derived origin for skin mural cells.

Project description:Follicular somatic cells (mural granulosa cells and cumulus cells) and the oocyte communicate through paracrine interactions and through direct gap junctions between oocyte and cumulus cells. Considering that mural and cumulus cells arise through a common developmental pathway and that their differentiation is essential to reproductive success, understanding how these cells differ is a key aspect to understanding their critical functions. Changes in global gene expression before and after an ovulatory stimulus were compared between cumulus and mural granulosa cells to test the hypothesis that mural and cumulus cells are highly differentiated at the time of an ovulatory stimulus and further differentiate during the periovulatory interval. The transcriptomes of the two cell types were markedly different (>1500 genes) before an ovulatory hCG bolus but converged after ovulation to become completely overlapping. The predominant transition was for the cumulus cells to become more like mural cells after hCG. This indicates that the differentiated phenotype of the cumulus cell is not stable and irreversibly established but may rather be an ongoing physiological response to the oocyte. We compared transcriptomes of mural granulosa cells isolated from the follicles before (PM-GC) and after (VVM-GC) an ovulatory stimulus. These data were analyzed with previously published cumulus cells data to compare transitions in granulosa cell state before and after an ovulatory stimulus with transitions in cumulus cells.

Project description:Mural cells are essential to the proper function of microvasculatures. However, the feasible cell source for mural cells has not been found, which is one of the key obstacles facedin tissue engineering. Our data show that circulating fibrocytes (CFs) sheathed and stabilized the microvasculatures formed by vascular endothelial cells (VECs) in collagen gel, formed gap junctions with VECs, and induced formation of basement membrane. When transplanted into nude mice with VECs either in collagen gel or Matrigel, CFs sheathed the microvasculatures formed by VECs, induced basal membrane formation and the microvasculatures connected to the host circulation. Human brain pericytes (HBPCs) had similar function to CFs, but HBPCs often mosaic into the lumen of capillary-like structures, actively proliferate, and have lower capacity of endocytosis and migration. Based on these data, we concluded thatCFs can be used as the cell source for mural cells to generate tissue-engineered microvasculatures
