Parenchymal pericytes are not the major contributor of extracellular matrix in the fibrotic scar after stroke in male mice
Scar formation after injury of the brain or spinal cord is a common event. While glial scar formation by astrocytes has been extensively studied, much less is known about the fibrotic scar, in particular after stroke. Platelet-derived growth factor receptor ß-expressing (PDGFRß+) pericytes have been suggested as a source of the fibrotic scar depositing fibrous extracellular matrix (ECM) proteins a
