Project description:We performed scRNA-seq of cells obtained with a protocol designed to capture all of the collagen-producing cells from normal and fibrotic mouse and human lungs.
Project description:To further understand the pathologic microenvironment in IPF, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish normal and IPF lung in normal-looking, fibrotic foci and hyperplastic areas of IPF lung. Four IPF lungs were dissected into normal-looking, fibrotic foci and hyperplastic areas by Laser-Capture-Microdissection. Gene expression analysis showed that 638 significantly different genes were identified that clearly distinguished the different IPF microenvironments . Among them, MMP19 was revealed as one of the most significantly up-regulated genes that distinguished normal looking epithelial cells (N) to hyperplastic epithelial cells, MMP19 up-regulation in IPF lungs was verified by immunohistochemical (IHC), qRT-PCR and Western-blot. IPF lungs are heterogeneity complex, which comprise normal looking area, fibrotic foci and hyperplastic area. In this study we separated the normal, fibrotic foci and hyperplastic area by LCM and employed Agilent whole genome gene expression microarray profiling to identify genes with the potential to distinguish the unique microenironment of IPF
Project description:In this study, adult virgin female BALB/C mice were kidney and lungs were harvested for RNA extraction (healthy kidney and lung). Adult virgin female BALB/C mice were subjected to unilateral ureter obstruction (UUO) to induce kidney fibrosis and the fibrotic kidney was harvested for RNA extraction. Adult virgin female BALB/C mice were subjected to intratracheal administration of bleomycine to induce lung fibrosis and the fibrotic lungs was harvested for RNA extraction.

Project description:QC, integration, mesenchymal fraction extraction and purity confirmation were performed as described previously. The mesenchymal cell subpopulations identified in the aged normal and fibrotic lungs were similar to those identified in adult mouse lungs and each cluster showed a distinct gene expression profile.
Project description:Using, scRNA Seq transcriptomic analysis, we report that Pdgra+ fibroblasts in mouse lung have significant heterogenity in normal and fibrotic lung, and key pathways involved in lipogenic and fibrogenic pathways govern the transition of normal lipofibroblasts from a normal to a myofibroblast phenotype following lung injury
Project description:We performed single-cell RNAseq for adult mouse fibrotic kidney to characheterize how epithelial to mesenchymal transition program is implemented at single tubular cells resolution during the course of renal intrestitial fibrosis
