Genetic lineage tracing defines myofibroblast origin and function in the injured heart
2016
The origin and fate of myofibroblasts, the cells responsible for cardiac remodelling and fibrosis, is controversial. Here the authors show that cardiac myofibroblasts express periostin, derive exclusively from tissue-resident fibroblasts, are necessary for scar formation after injury, and can revert back to a less-activated state upon injury resolution.
