A team of Spanish biologists has created a prototype 3D bioprinter that reproduces functional human skin, which will make it possible to further abandon animal experiments.
It is a joint project of the University of Madrid, the Center for Energy and the Environment, and the Gregorio Marañon University Hospital. Scientists have been able to print skin suitable for burn grafts, chemicals and cosmetics.
The created bioprinter accurately reproduces real human skin. Even the layers are imitated: the outer epidermis, a thick layer of the dermis, a layer of fibroblast cells that produce collagen and protein, which endow the skin with elasticity and strength.
“Knowing how to combine biological elements with each other, under what conditions to do it so that cells do not die, correct storage - everything is critical for the result, ” explains one of the project participants, Juan Francisco del Cañiso.
According to the head of the BioDan group, which will be engaged in the commercial advancement of the technology, Alfredo Brizac, the technology of bioprinting will make it possible to obtain leather in an automatic mode, which is much cheaper than manually.
