Myofibroblasts and scar
WebJul 20, 2024 · Myofibroblasts are thought to be the main cell type responsible for producing the proteins that form scar tissue. Further work showed that the creation of new myofibroblasts was triggered by the flexible scar tissue itself through proteins called integrins. Integrins are receptors on the surface of cells that can sense mechanical forces.

WebNational Center for Biotechnology Information WebJun 21, 2016 · In response, the majority of myofibroblasts are removed from the scarred area, possibly through apoptosis. Moreover, the vascular cells die, and the temporary microvasculature is disintegrated. Whether active inhibitory signaling is involved in suppressing the fibrotic response is unclear.
WebJan 14, 2024 · Background: Inhibiting proliferation and inducing apoptosis of myofibroblasts is becoming one of the promising and effective ways to treat hypertrophic scar. ABT-263, as an orally bioavailable BCL-2 family inhibitor, has showed great antitumor characteristics by targeting tumor cell apoptosis. The objective of this study was to explore whether ABT …
WebAug 6, 2013 · The relative contribution and role of scar-forming myofibroblasts of extrarenal origin is another component of the myofibroblast controversy that remains unresolved. WebNov 23, 2024 · Fibroblasts deposit extracellular matrix (ECM) molecules to regulate tissue strength and function. However, if too much ECM is deposited, fibrosis and scarring results. Shook et al. examined cells during mouse skin wound healing, fibrosis, and aging (see the Perspective by Willenborg and Eming).
WebDec 23, 2024 · Myofibroblasts secrete more ECM (mainly collagen and Fn) and contract the wound bed. However, unchecked myofibroblasts can lead to fibrosis. Afterward, keratinocytes migrate over the newly produced ECM and release vascular endothelial …
