AI Article Synopsis

  • Pdgfra+ oligodendrocyte precursor cells (OPCs) develop in distinct waves during embryonic development in the central nervous system (CNS), but their relationship to different adult oligodendrocyte states is not well understood.
  • Research utilizing bulk and single-cell transcriptomics reveals that post-natal OPCs from both the brain and spinal cord share similar transcriptional patterns, indicating a degree of similarity in their development.
  • Additionally, some E13.5 Pdgfra+ cells were found to derive from the pericyte lineage, suggesting that these embryonic cells contribute to various post-natal cell types, including OPCs, across different regions of the CNS.

Article Abstract

Pdgfra+ oligodendrocyte precursor cells (OPCs) arise in distinct specification waves during embryogenesis in the central nervous system (CNS). It is unclear whether there is a correlation between these waves and different oligodendrocyte (OL) states at adult stages. Here, we present bulk and single-cell transcriptomics resources providing insights on how transitions between these states occur. We found that post-natal OPCs from brain and spinal cord present similar transcriptional signatures. Moreover, post-natal OPC progeny of E13.5 Pdgfra+ cells present electrophysiological and transcriptional profiles similar to OPCs derived from subsequent specification waves, indicating that Pdgfra+ pre-OPCs rewire their transcriptional network during development. Single-cell RNA-seq and lineage tracing indicates that a subset of E13.5 Pdgfra+ cells originates cells of the pericyte lineage. Thus, our results indicate that embryonic Pdgfra+ cells in the CNS give rise to distinct post-natal cell lineages, including OPCs with convergent transcriptional profiles in different CNS regions.

IDH-mutant low-grade gliomas (LGGs) are slow-growing brain tumors that frequently progress to aggressive high-grade gliomas that have dismal outcomes. In a recent study, Wu and colleagues provide critical insights into the mechanisms underlying malignant progression by analyzing single-cell gene expression and chromatin accessibility across different tumor grades. Their findings support a two-phase model: in early stages, tumors are primarily driven by oligodendrocyte precursor-like cells and epigenetic alterations that silence tumor suppressors like CDKN2A and activate oncogenes such as PDGFRA.

Endothelial-secreted Endocan activates PDGFRA and regulates vascularity and spatial phenotype in glioblastoma.

Extensive neovascularization is a hallmark of glioblastoma (GBM). In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Canine high-grade oligodendrogliomas (HGOGs) exhibit a high expression of platelet-derived growth factor receptor-α (PDGFRA). We examined mutations and gain of and their association with the PDGFRA expression and proliferation of tumor cells in canine HGOG cases and cell lines. Polymerase chain reaction and sequence analysis revealed expected pathogenic mutations in exons 7 and 8 in 16/34 (47%) cases.

Background: Spinal cord injury (SCI) inflicts a severe burden on patients and lacks effective treatments. Owing to the poor regenerative capabilities of endogenous oligodendrocyte precursor cells (OPCs) following SCI, there is a growing interest in alternative sources, such as human umbilical cord mesenchymal stem cells (HUCMSCs). TET3 is a key DNA demethylase that plays an important role in neural differentiation, but its role in OPC formation is not well understood.

Article Synopsis
  • - The study focuses on cancer-associated fibroblasts (CAF) in tumors, particularly looking at the markers FAP and PDGFR in bladder and prostate cancers, noting the complexity and variation of CAF functions in tumor development.
  • - Researchers analyzed tissue samples from 34 prostate cancer patients and 44 bladder cancer patients to identify the relationship between CAF markers and cancer characteristics like stage, morphology, and survival.
  • - Findings show that FAP is linked to metastasis and recurrence in prostate cancer, while its presence is exclusive to invasive bladder cancers, highlighting FAP's potential as a significant marker for diagnosing and understanding treatment resistance in genitourinary tumors.
