Project description:We used microarrays to detail the transcriptome-wide gene expression changes underlying chemical conversion of human fibroblasts into induced Schwann Cells over a time period of 39 days. We compared then the expression profiles of these induced Schwann Cells to primary Schwann cells. The gene expression results analyzed in this study are further described in Thoma et al. (2014) Chemical conversion of human fibroblasts into functional Schwann cells. Under submission
Project description:We report the generation of myelinating human oligodendrocytes from dermal fibroblasts using a direct lineage conversion technique.
Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.
Project description:Peripheral nerves contain axons and their enwrapping glia cells named Schwann cells (SC) that are either myelinating or non-myelinating (nmSC). Our understanding of other cells in the peripheral nervous system (PNS) remains limited. Here, we provide an unbiased single-cell transcriptomic characterization of the non-diseased rodent PNS. We identified and independently confirmed novel markers of previously underappreciated nmSC and nerve-associated fibroblasts. We also found and characterized two distinct populations of nerve-resident homeostatic myeloid cells that transcriptionally differed from central nervous system microglia. In a model of chronic autoimmune neuritis, homeostatic myeloid cells were outnumbered by infiltrating lymphocytes which modulated the local cell-cell interactome and induced a specific transcriptional response in glia cells. This response was partially shared between the peripheral and central nervous system glia identifying common immunological features across different parts of the nervous system. Our study thus identifies novel subtypes and cell-type markers of PNS cells and a partially conserved autoimmunity module induced in glia cells.
Project description:RNA sequencing of sorted mouse Schwann cells expressing YFP due to P0Cre-mediated recombination. The plotting of side scatter versus eYFP fluorescence generates 2 semi-detached eYFP+ clouds of cells, which further enables the enriched selection of myelinating Schwann cells, and of not-myelinating Schwann cells.
