Single-cell transcriptomics reveals early emergence of liver parenchymal and non-parenchymal cell lineages

Project description:To characterize the heterogeneity within endothelial, mesenchymal, and hepatic lineages through formation of the embryonic mouse liver bud, we have performed single-cell RNA sequencing on mouse embryos, spanning days 9.5 to 10.5 of development. This data set includes 12,470 cells with a mean detected gene number of 4,588.

Early fate defines microglia and non-parenchymal brain macrophage development

Project description:Central nervous system (CNS) macrophages comprise parenchymal microglia and border-associated macrophages (BAMs) residing in the meninges, the choroid plexus and the perivascular spaces. With the exception of choroid plexus macrophages, most CNS macrophages emerge during primitive hematopoiesis in the extra-embryonic yolk sac. What remains unknown however, is whether microglia and BAMs share a developmental program or arise from separate predefined lineages. Here, we identified two phenotypically, transcriptionally and locally distinct brain macrophage populations throughout development, giving rise to microglia and BAMs. Two independent macrophage populations were already present in the yolk sac prior to their seeding of the brain. Using fate-mapping system, we demonstrate that in contrast to microglia, the pool of embryonic BAMs in the choroid plexus and the meninges was gradually replaced by precursors emerging later in embryogenesis. The development of microglia was dependent on TGF-β whereas the genesis and maturation of BAMs occurred independently of this cytokine. Collectively, our data show that developing parenchymal and non-parenchymal brain macrophages are separate entities in terms of ontogeny, gene expression signatures and requirement for TGF-β.

A549 parenchymal cell activation

Project description:Alveolar epithalial cells (A549) were used as a model of pulmonary parenchymal cell activation to quiery gene expression profile of activation with either cyclic stretch (20% elongation), TNF (20 ng/ml), LPS (1 mcg/ml) or TNF+STRETCH at both 1 and 4 hrs. Keywords: time-course

Single-cell RNA sequencing of liver parenchymal cells from murine model of endotoxemia

Project description:Liver has a crucial role in the regulation of immune defense in systemic infections. During endotoxemia, the liver transits from an immune-tolerant towards an immune-active state and forms the first line of defense against invading microorganisms. the role of liver parenchymal cells in endotoxemia remains unintelligible. To characterize the liver parenchymal cells in endotoxemia liver, we performed single-cell RNA sequencing of liver parenchymal cells from healthy C57BL/6J mice and murine model of endotoxemia at early or late stage. The single-cell RNA-seq analyses revealed the heterogeneity of liver parenchymal cells in endotoxemia liver.

PDGFRα and αSMA mark two distinct mesenchymal cell populations involved in parenchymal and vascular remodeling in pulmonary fibrosis

Project description:We utilized a fate-mapping approach to investigate alpha-smooth muscle actin (αSMA)+ and platelet derived growth factor-alpha (PDGFRα)+ cells in two lung fibrosis models, complemented by cell-type specific next-generation sequencing and investigations on human lungs. Our data revealed that αSMA+ and PDGFRα+ cells mark two distinct mesenchymal lineages with minimal transdifferention potential during lung fibrotic remodeling. Parenchymal and perivascular fibrotic regions were populated predominantly with PDGFRα+ cells expressing collagen, while αSMA+ cells in the parenchyma and vessel wall showed variable expression of collagen and the contractile protein desmin. The distinct gene expression profiles found in normal conditions was retained during pathologic remodeling. Cumulatively, our findings identify αSMA+ and PDGFRα+ cells as two separate lineages with distinct gene expression profile in adult lungs.

Cell-to-cell gene expression variability followed by reinforcement progressively segregates lineages in the early mouse embryo

Project description:Mammalian embryonic development begins with the specification and segregation of the two extra-embryonic lineages, trophectoderm and primitive endoderm, from the pluripotent embryonic lineage, the epiblast. To establish a map of epiblast (EPI) versus primitive endoderm (PrE) lineage segregation which occurs within the inner cell mass (ICM), we comprehensively characterised the gene expression profiles of individual inner cells during blastocyst development. Lineage represents the two embryonic cell lineages: the epiblast (EPI), and the primitive endoderm (PE), which are segregated within the inner cell mass(ICM) during blastocyst development.
