Wound healing enhancement in leg ulcers: A case report.

Wound healing in the skin is a complex biological process in which numerous types of cells, cytokines, growth factors, proteases and extracellular matrix components act in concert to restore the integrity of injured tissue. Cultivated allogenic human keratinocytes have been used for the treatment of various skin defects like burnwounds, surgical wounds, in exfoliative skin diseases and chronic wounds. A new method for wound healing enhancement in leg ulcers using cultured allogenic keratinocytes suspended in fibrin glue and used in spray technique is introduced. Allogenic keratinocytes are supposed to enhance granulation tissue production and to stimulate reepithelisation due to their release of growth factors and thus are able to recreate an active wound.
