Spanish scientists "have generated artificial human skin by [tissue] engineering based on agarose-fibrin biomaterial. The artificial skin was grafted onto mice, and optimal development, maturation and functionality results were obtained. This pioneering finding will allow the clinical use of human skin and its use in many laboratory tests on biological tissues - which, additionally, would avoid the use of laboratory animals. Further, this finding could be useful in developing new treatment approaches for dermatological pathologies. ... The skin created in the laboratory showed adequate biocompatibility rates with the recipient and no rejection, dehiscence or infection was registered. ... The experiment [is] the first to create artificial human skin with a dermis made of fibrin-agarose biomaterial. To this date, artificial skin substitutes were elaborated with other biomaterials as collagen, fibrin, polyglycolic acid, chitosan, etc. These biomaterials [added] resistance, firmness and elasticity to the skin. ... Definitively, we have created a more stable skin with similar functionality to normal human skin."
