Organ fibrosis often leads to end-stage organ failure, but the origin of key profibrotic cell types is still unclear. Lucie Peduto and her colleagues have used genetic lineage tracing and pharmacological ablation techniques to show that ADAM12+ perivascular cells are a key source of profibrotic cells in acute skin and muscle injury in the mouse. They also show that knockdown of ADAM12 expression is beneficial, suggesting a possible therapeutic target for the treatment of fibrosis.
