Abstract
Rapid progress of in vitro techniques in the lastyears enabled the creation of organotypic skin cultures offering newpossibilities in wound treatment. Rebuilding of graft is one of the keyelementsof successful outcome of the procedure.In search for the best scaffold for organotypic skin culture, the novelcomposite xenogenic collagen based material with unique properties has beencreated and used to reconstitute full thickness human skin invitro. Based on our long established technology used for theproduction of collagen dressings for the treatment of burns, this novel,composite material offers excellent growth support of highly biodegradablespongy layer, combined with mechanical strength of collagen membrane. Themodulation of collagen properties was accomplished by consecutive treatmentwithhigh temperature and gamma irradiation. The use of the substrate enabled toobtain organotypic culture that resembles full thickness skin with fibroblastslayer and well-developed multilayer epithelium. Our new material offers easyhandling of obtained graft during surgery along with accelerated cell growth andcontrolled biodegradation of the culture support.
