Pericytes and perivascular fibroblasts contribute to central nervous system fibrosis in a region dependent manner (DH express)
Ontology highlight
ABSTRACT: Fibrotic scar tissue formation is conserved throughout the central nervous system in humans and mice, and impairs tissue regeneration and functional recovery. However, the origin of scar-forming stromal fibroblasts is controversial. Here, we show that stromal fibroblasts found after spinal cord injury derive from two populations of perivascular cells that are anatomically and transcriptionally defined as pericytes and perivascular fibroblasts. We identify two distinct perivascular cell populations, which activate and transcriptionally converge on the generation of stromal myofibroblasts after injury. Our results suggest potential targets to improve tissue regeneration and functional recovery after central nervous system injuries.
