Macrophages mediate the fibrotic response after a heart attack by extracellular matrix turnover and cardiac fibroblasts activation. Here the authors identify an evolutionarily-conserved function of macrophages that contributes directly to the forming post-injury scar through cell-autonomous deposition of collagen.
