Scar muscular power and possibly heart failure. However, there are some tissues (e.g. bone) that can heal without any structural or functional deterioration. All scarring is composed of the same collagen as the tissue it has replaced, but the composition of the scar tissue, compared to the normal tissue, is different. Scar tissue also lacks elasticity unlike normal tissue which distributes fiber elasticity. Scars differ in the amounts of collagen overexpressed. Labels have been applied to the differences in overexpression. Two of the most common types are hypertrophic and keloid scarring, both of which experience excessive stiff collagen bundled growth overextending
Oral mucosa tissue engineering for controlling connective tissue formation. Examples of synthetic scaffolds are: Historical use of electrospinning to produce synthetic scaffolds dates back to at least the late 1980s when Simon showed that technology could be used to produced nano- and submicron-scale fibrous scaffolds from polymer solutions specifically intended for use as "in vitro" cell and tissue substrates. This early use of electrospun lattices for cell culture and tissue engineering showed that various cell types would adhere to and proliferate upon polycarbonate fibers. It was noted that as opposed to the flattened morphology typically seen in 2D culture, cells grown on the electrospun
