"PDGFRα is required for postnatal cerebral perivascular fibroblast development".

ABSTRACT: Perivascular fibroblasts (PVFs) are a cell type associated with large diameter blood vessels in the brain and spinal cord parenchyma and leptomeninges. PVFs have previously defined roles in injury and neuroinflammatory diseases and predicted roles in supporting neurovascular function. The temporal dynamics of PVF development in the pre- and postnatal cerebral cortex have recently been described, however the molecular mechanisms that underly PVF development have not been identified. PVFs express both platelet derived growth factor receptors (PDGFRs), PDGFRα and PDGFRβ. Here we investigate the role of PDGF signaling in PVF development. We use immunohistochemistry and RNA transcript detection methods to show developmental expression of PDGFRs by PVFs and examine distribution of PDGF ligand ex
