In some cells at least, there is cross talk between hypoxia signaling and TGF-β signaling that may exacerbate matrix synthesis and thus fibrosis.63,64. 2012;180(4):1340–1355. Initially the wound is hypoxic due to the loss of vascular perfusion, but with the development of a new capillary network, vascular perfusion is restored. In vitro wound healing assay. Essentially, wound healing occurs through three main stages that include the inflammatory phase, the proliferative phase, as well as the regeneration phase. During normal healing, this hypoxia is resolved within a few days of injury and expression of HIF-1α declines. GR appears to affect fibroblast activation and modulate the expression of proteins involved in tissue remodeling. Considering that SPMs have significant actions on regulation of wound healing in inflammatory diseases, we hypothesized that amplification of resolution of inflammation pathways during wound healing will regulate fibroblast function, modulate fibroblast migration and proliferation… Hair follicle dermal sheath cells: unsung participants in wound healing. Figure 5 The interactions between the dermis and the epidermis.Notes: The dermis and the epidermis contain nerves, but only the dermis is vascularized. However, the molecular mechanisms determining the reparative response of fibroblasts remain unknown. Differential contribution of dermal resident and bone marrow-derived cells to collagen production during wound healing and fibrogenesis in mice. 2005;13(4):398–404. Leask A, Abraham DJ. Inhibition of systemic sclerosis dermal fibroblast type I collagen production and gene expression by simvastatin. Following damage to the capillaries, a blood clot starts forming in order to prevent further bleeding. Hao H, Gabbiani G, Camenzind E, Bacchetta M, Virmani R, Bochaton-Piallat ML. 2007;21(12):3250–3261. 2004;15(9):4310–4320. In cancer biology, matrix stiffness can be used as a diagnostic indicator of the risk of malignancy and appears to correlate with increased invasiveness of tumors, for example in breast cancer where density of tissue on mammography correlates strongly with the risk of cancer formation. 2004;117(Pt 5):667–675. J Cell Biol. Fibroblasts are broadly defined as connective-tissue-resident cells that produce the extracellular matrix (ECM) scaffolding of the body. Dynamic reciprocity in the wound microenvironment. Experientia. Eur J Cell Biol. Hinz B, Gabbiani G. Fibrosis: recent advances in myofibroblast biology and new therapeutic perspectives. Volume 2014:7 Pages 301—311, Editor who approved publication: Platelets present in the blood clot release multiple chemokines, which participate in the recruitment of inflammatory cells, neutrophils, and macrophages, but also in chemotaxis and recruitment of fibroblasts and endothelial cells. Myofibroblasts can, depending on the experimental or clinical situation, express other SM-related contractile proteins, such as SM myosin heavy chains or desmin; however, the presence of α-SM actin represents the most reliable marker of the myofibroblastic phenotype.27 The third phase of healing, scar formation, involves a progressive remodeling of the granulation tissue. TGF-beta signaling and the fibrotic response. Biomed Res Int. Hinz B. Thromb Haemost. 2005;37(3–4):231–296. Myofibroblasts are implicated in many fibrotic and scarring diseases, where they carry out the important process after initial injury of providing mechanical support and integrity to the tissue. Number 3099067. 2004;48(5–6):509–517. Serini G, Bochaton-Piallat ML, Ropraz P, et al.

In addition, the (myo)fibroblast phenotype is regulated by mechanical stresses to which they are subjected and thus by mechanical signaling. As the growth factor TGF-β is central to many of the mechanisms of pathological scarring and fibrosis, it has been the target of some therapeutic strategies. Yeung T, Georges PC, Flanagan LA, et al.
