Project description:A protocol was established for the derivation of Schwann cell-like cells from human BMSCs. The commitment to the Schwann cell fate was acquired by Schwann cell-like cells in co-culture with rat DRG neurons. Microarray analysis provided evidence that the human BMSC-derived Schwann cells were functionally mature.

Project description:Recent reports of directed reprogramming have raised questions about the stability of cell lineages. Here, we have addressed this issue, focusing upon skin-derived precursors (SKPs), a dermally-derived precursor cell. We show by lineage tracing that murine SKPs from dorsal skin originate from mesenchymal and not neural crest-derived cells. These mesenchymally-derived SKPs can, without genetic manipulation, generate functional Schwann cells, a neural crest cell type, and are highly similar at the transcriptional level to Schwann cells isolated from the peripheral nerve. This is not a mouse-specific phenomenon, since human SKPs that are highly similar at the transcriptome level can be made from facial (neural crest-derived) and foreskin (mesodermally-derived) dermis, and the mesodermally-derived SKPs can make myelinating Schwann cells. Thus, non-neural crest-derived mesenchymal precursors can differentiate into bona fide peripheral glia in the absence of genetic manipulation, suggesting that developmentally-defined lineage boundaries are more flexible than widely thought. We obtained 3 independent samples of nerve Schwann cells, SKP-derived Schwann cells, and Dorsal Trunk SKPs, each, from adult SD rats. Primary cells were isolated and cultured, and RNA was collected from those cultured samples. RNA samples deriving from these cells were analyzed on the Affymetrix Rat Gene 1.0 ST Array.

Project description:Schwann cells are critical for the proper development and function of the peripheral nervous system, where they form a collaborative relationship with axons. Past studies highlighted that a pair of proteins called the prohibitins play major roles in Schwann cell biology. Prohibitins are ubiquitously expressed and versatile proteins. We have previously shown that while prohibitins play a crucial role in Schwann cell mitochondria for long-term myelin maintenance and axon health, they may also be present at the Schwann cell-axon interface during development. The current data set uses BioID to identify a pool of candidate PHB2 interactors in Schwann cells and explores how the PHB2 interactome changes depending on neuronal signals. We expressed a PHB2-turboID fusion construct in primary rat Schwann cells; turboID is a 35 kDa engineered biotin ligase that rapidly biotinylates proximal proteins. Thus, proteins interacting with PHB2-turboID within an approximately 10 nm radius are tagged with biotin. As a control, primary rat Schwann cells were transfected with an unfused turboID construct (Con-turboID). Schwann cells expressing Con-turboID or PHB2-turboID were plated alone or onto primary rat DRG neurons, in the presence or absence of biotin. After 2 hours, proteins were harvested from the cultures and biotinylated proteins were purified using streptavidin-affinity purification (AP). We then used liquid chromatography-mass spectrometry (LC-MS) to identify the PHB2-turboID interactors (the biotinylated proteins) in our purified pool. The PHB2 interactors identified here, especially those which increase or decrease interaction with PHB2-turboID in the presence of neurons, may play a role in prohibitin-associated Schwann cell-axon communication.

Project description:We utilized RNA-Seq on rat Schwann (S16) cells to determine global gene expression. This information was generated as part of a larger effort to characterize cis-regulatory elements and global gene expression within Schwann cells. To achieve this, we generated RPKM values across two independent biological replicates. This dataset was also used to predict cis-regulatory element function on genes following CRISPR knockout studies.

Project description:Due to limited availability of proper models to study keloid development, the underlying pathomechanisms of this severe skin disease is still poorly understood. Here we performed single-cell sequencing of keloids and identified the occurrence of a so far unrecognized keloidal Schwann cell population, remaining in the scar tissue after wound healing. In contrast to normal skin, keloidal Schwann cells possess a repair-like phenotype and high cellular plasticity. Our data reveal that keloidal Schwann cells directly contribute to the formation of the extracellular matrix and affect M2 polarization of macrophages. Indeed, we show that macrophages in keloids predominantly display a M2 polarization and produce factors inhibiting Schwann cell differentiation. Our data suggest that this cross-talk contribute to the infinite growth of keloids and that targeting Schwann cells might represent a novel treatment option for keloids.

Project description:The aim of this study was to identify differently expressed genes between C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cells. To elucidate the unresolved mechanism behind the promoting effect of C3156-181 on PNR we cultured primary rat neonatal SCs and treated them for up to 72 h with C3 or C3156-181. We then performed gene expression microarray analysis Results from two loops of two different treatment times are summarized in this study. The samples were taken from two C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cell cultures. Microarrays were hybridized in a loop approach. Results from two loops that map to two different sampling times (loop1: after 12 hours, loop2: after 72) are compared in this study. The data in this file represents loop1. The samples were taken from untreated, C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cells.
