Macrophages may have proinflammatory or antiinflammatory properties, but which properties influence fibrosis remains unclear. To explore the role of macrophages in liver fibrosis, we performed single-cell RNA-seq in a mouse model of liver injury and found that macrophage diversity was increased.\n                    <jats:italic>Marco<\/jats:italic>\n                    was among the most significantly upregulated genes, and a population of\n                    <jats:italic>Marco<\/jats:italic>\n                    <jats:sup>hi<\/jats:sup>\n                    macrophages increased with injury and spatially segregated to nonfibrotic areas. The macrophage receptor with collagenous structure (MARCO) protein is a scavenger receptor expressed by specific subsets of macrophages, and its role in liver fibrosis is unclear. In vitro induction of\n                    <jats:italic>Marco<\/jats:italic>\n                    in bone marrow\u2013derived macrophages decreased proinflammatory gene expression, increased antiinflammatory and antifibrotic gene expression, and enhanced phagocytosis, indicating a restorative phenotype.
