The discovery of the myofibroblast has allowed definition of the cell responsible for wound contraction and for the development of fibrotic changes. This short review puts a spotlight on the myofibroblast for those who seek therapeutic targets in the context of dysregulated tissue repair. Shao H, Li Y, Pastar I, Xiao M, Prokupets R, Liu S, Yu K, Vazquez-Padron RI, Tomic-Canic M, Velazquez OC, Liu ZJ. Current Research in Translational Medicine, https://doi.org/10.1016/j.retram.2016.09.003. USA.gov. Too many myofibroblasts working for too long cause tissue contractures that ultimately obstruct organ function. Intact healthy skin protects the body from outside threats; therefore, proper wound healing is an essential process in response to tissue damage 1–3.The formation of a scar comprises a crucial part of normal mammalian tissue repair but defects in its resolution can lead to excessive accumulation of extracellular matrix (ECM) in the tissue and cause pathological scarring. However, in pathological conditions, myofibroblasts persist and secrete excessive amounts of aberrant extracellular matrix proteins (fibrosis) resulting in corneal scarring. The role of myofibroblasts in wound healing 1. eCollection 2020. Keywords: myofibroblast, fibroblast, α-smooth muscle actin, mechanical signaling, fibrosis, scarring Introduction to the myofibroblastic phenotype Myofibroblasts were first described in healing skin wounds, where it was hypothesized that they were responsible for the phenomenon of wound contraction.1 Since then, All rights reserved. Repair of tissue following injury involves dynamic interactions between multiple cell types, growth factors, inflammatory mediators and components of the extracellular Myofibroblast activity can be physiological, e.g., regulation of ventilation/perfusion ratio in pulmonary alveoli, and useful for wound healing but noxious in … Following tissue injury, tissue repair takes place in well-characterized steps. Too many myofibroblasts working for too long cause tissue contractures that ultimately obstruct organ function. New insights into the roles of myofibroblasts and innervation during skin healing and innovative therapies to improve scar innervation. Fibrosis. Curiously, these same risk factors also sign responsible for the development of hypertrophic scarring and organ fibrosis. Activated repair cells - myofibroblasts - are the main producers and organizers of extracellular matrix which is needed to restore tissue integrity after injury. The stellate cell to myofibroblast transformation process, also known as “activation” - in which Acta2 is an integral component - appears to be analogous to that occurring in fibroblasts after injury and wound healing in other pathological settings, –. Life Sci Alliance. Would you like email updates of new search results? 2018 Aug;68-69:81-93. doi: 10.1016/j.matbio.2018.01.019. TGF-β1 is an integral activator of the myofibroblast phenotype during wound healing processes. Sarrazy V, Billet F, Micallef L, Coulomb B, Desmoulière A. Insufficient myofibroblast activation and activities, in turn, prevents normal wound healing. The transition from fibroblasts to myofibroblasts is influenced by mechanical stress, TGF-beta and cellular fibronectin (ED-A … Contraction. The various phases of the healing process.  |  Immediately after wounding, the healing process commences, leading to (partial) restoration of injured tissue. 2020 Jul 29;8:697. doi: 10.3389/fcell.2020.00697. 43 This phenotypic change is marked by the de novo induction of α-SMA expression and its localization to stress fibers. Notes: After damage, inflammation leads to the formation of the granulation tissue, during which myofibroblasts appear. The importance of proper skin wound healing becomes evident when our body's repair mechanisms fail, leading to either non-healing (chronic) wounds or excessive repair (fibrosis). COVID-19 is an emerging, rapidly evolving situation. HHS Exp Eye Res. The inability to find a single molecular marker that identifies all activated “myofibroblasts” during wound healing suggests the existence of multiple subsets of ECM-producing myofibroblasts. TGF‐β 1 is the major growth factor inducing myofibroblast (Desmoulière et al , 1993) and vascular smooth muscle‐cell differentiation (Majesky et al , 1991) during wound healing. 1 Department of Surgery, Alfaisal University, Riyadh, Saudi Arabia. 2020 Dec;42(6):1475-1498. doi: 10.1007/s11357-020-00279-w. Epub 2020 Oct 6. Please enable it to take advantage of the complete set of features! The clinical relevance of each step is then discussed in the form of modalities to prevent excessive scarring/fibrosis. Lebonvallet N, Laverdet B, Misery L, Desmoulière A, Girard D. Exp Dermatol. Wound healing more broadly is a … Ahangar P, Mills SJ, Smith LE, Gronthos S, Cowin AJ. The... 2. myofibroblast activity represent the fourth step. In wounds healing by secondary intention, myofibroblasts persist in the granulation tissue producing collagen and mediating wound contraction . Myofibroblasts synthesize extracellular matrix components such as collagen types I and III and during normal wound healing disappear by apoptosis when epithelialization occurs. Fibroblast differentiation in wound healing and fibrosis. During physiological wound healing, myofibroblasts disappear by apoptosis and tissue transparency is maintained. 2020 Dec 10;5(1):24. doi: 10.1038/s41536-020-00109-9. Candidate rejuvenating factor GDF11 and tissue fibrosis: friend or foe? ... of the wound •Role of myofibroblast . The role of myofibroblasts in wound healing. Insufficient myofibroblast activation and activities, in turn, prevents normal wound healing.
