Project description:Ahead of display, a non-original layer was observed on the surface of a fragment of a wall painting by Ambrogio Lorenzetti (active 1319, died 1348/9). FTIR analysis suggested proteinaceous content. Mass spectrometry was used to better characterise this layer and revealed two protein components: sheep and cow glue and chicken and mallard egg white. Analysis of posttranslational modifications detected several photo-oxidation products, which suggest that the egg experienced prolonged exposure to UV-light and was likely applied long before the addition of the glue. Additionally, glycation products detected may indicate naturally occurring glycoprotein degradation or reaction with a carbohydrate material such as starch, identified by ATR-FTIR in a cross-section of a sample taken from the painting. Palaeoproteomics is shown to provide detailed characterisation of organic layers associated with mural paintings and therefore aids reconstruction of the conservation history of these objects.

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.
