Hypertrophic scarring is abnormal proliferation of dermal fibroblasts and excessive deposition of extracellular matrix. To date, despite many studies, treatments have not been satisfactory. Genistein, a potent, specific inhibitor of tyrosine protein kinases (TPKs), has been proved to inhibit many kinds of tumour and some fibrotic diseases. The purpose of this study was to investigate the effects of...
Over production of collagen and its abnormal assembly is the hallmark of abnormal scars such as keloids, a condition which reflects fibrosis of the skin. Fibrotic conditions of organs such as liver, lungs and eyes are characterized by low levels of decorin, a member of the small leucine proteoglycan family, which is an indispensable modulator of collagen assembly. Involvement of decorin in keloids...
Fibroblasts are thought to be partially responsible for the persisting contractile forces that result in burn contractures. Using a monolayer cell culture and fibroblast populated collagen lattice (FPCL) three-dimensional model we subjected hypertrophic scar and non-cicatricial fibroblasts to the antifibrogenic agent pentoxifylline (PTF – 1mg/mL) in order to reduce proliferation, collagen types I...
