Project description:Mesenchymal stem/stromal cells (MSCs) are supplied to the damaged tissue via circulation when the injury is massive. MSCs recruited to the damaged tissues support tissue regeneration by differentiating into parenchyma cells and suppressing inflammation. However, most of the analysis of the circulating MSCs have been conducted in adult models, the existence and properties in fetal circulation was not known. Here, we have extensively analyzed the circulating MSCs cells during development.
Project description:Comparsion of proteomes of Campylobacter fetus subsp. fetus to compare protein level via iBAQ analysis, expression (by LFQ) and coverage between Campylobacter fetus subsp. fetus strain82-40 vs Campylobacter fetus subsp. fetus strain ATCC 27374
Project description:The circulating leukocyte population contains a fraction of cells derived from progenitors that had transient PDGFRa expression during embryonic development (PDGFRa-lineage). During inflammation, extravasated leukocytes in inflamed tissue modify the tissue-resident leukocyte population and crosstalk with the stromal cells. The current study investigates the effects of extravasated leukocytes derived from PDGFRa-lineage origin on the skin in atopic dermatitis (AD). Lineage- bone marrow progenitors were isolated from PDGFRa-lineage labeling mice which labels cells derived from PDGFRa-lineage with tdTomato. Progenitors derived from PDGFRa-lineage or non-PDGFRa-lineage were transplanted to irradiated EGFP-transgenic mice and allowed for bone marrow reconstitution (BMT). AD was then induced by repeated topical application of MC903 for six times. On day 14, RNA was isolated from inflamed skin to construct library for bulk RNA sequencing. AD skin transcriptomes of PDGFRa-lineage and non-PDGFRa-lineage BMTs were compared. In addition, the obtained dataset were paired with flow cytometric measurement of leukocyte extravasation to compare samples with similar extravasation loads. We found via functional enrichment analyses that extravasated PDGFRa-lineage leukocytes possess intrinsic properties that differ from non-PDGFRa-lineage, coordinate stronger inflammatory responses and modulate the extracellular matrix.
Project description:In order to elucidate the developmental origin of oligodendrocyte precursor cells (OPCs) and get a better understanding of the several waves of OPC generation, we look at several timepoints and perform single-cell RNA-seq on Pdgfra positive populations in Mice.
Project description:We report the high-throughput profiling of thirteen human glioblastoma and four pairs of panned(pdgfra+) and supernatant(pdgfra-) human glioma cells. The subtypes and the different expression genes(DEGs) was identified integrated genomic analysis:single sample GSEA and DESeq.We obtained the enrichment gene pathway by using Gene Ontology Enrichment analysis-Functional classification viewed in pie chart.We find that the features of Proneural were enriched generaly when comparing the four pairs of the panned(pdgfra+) and supernatant(pdgfra-) human glioma cells.
