Tissue regeneration technology remarkably enhances skin repair via re-epidermalization, epidermal-stromal cell interactions, angiogenesis, and inhabitation of hypertrophic scars and keloids. Bioactive molecules are practical tools for regulating cellular processes and have been applied to control cellular differentiation, dedifferentiation, and reprogramming. Certain nutrients become even more important when your body is in need of repair. Tissue engineered skin substitutes for wound healing have evolved tremendously over the last couple of years. MAP gels, when applied to a wound, create a type of scaffolding that allows new skin tissue to latch on and grow within the cavities between the linked particles, reducing scarring. A scar is an area of fibrous tissue that replaces normal skin after an injury. Granulation tissue is a pathological term for the early appearances at the base of an ulcer or wound. The physiology of the skin largely functions to preserve itself and promote regeneration, both long-term and in response to acute injury. Consequently, the self-healing capacity of patients can be augmented by artificially enhancing one or more processes important for healing through the application of growth factors. Natural (acute) wound healing proceeds through several largely overlapping phases that involve an inflammatory response and associated cellular migration, proliferation, matrix deposition, and tissue remodeling (Fig. Wound debridement – the killing of bacteria and removal of necrotic (dead) tissue – is a key step in healing chronic wounds, most of which get infected in this way.
