A way found to print human skin



In every lab test that involves cells expecially animal cells, human or animal life is always used as a case of study. These scenarios have made these group of researchers to look for a way to avert this trending activities by creating a prototype 3D bioprinter that can create functional human skin.
The researchers, from Universidad Carlos III de Madrid, the Center for Energy, Environmental and Technological Research and Hospital General Universitario Gregorio Marañón, say their lab-made skin can be used in transplants for burns victims or for the testing of chemicals, cosmetics and pharmaceuticals.

According to one of the researchers, Juan Francisco del Cañizo, he said “Knowing how to mix the biological components, in what conditions to work with them so that the cells don’t deteriorate, and how to correctly deposit the product is critical to the system."
The composition of the skin looks like that of a human, having epidermis-like external layer for protection, a thicker layer to act as the dermis and a layer made up of fibroblast cells that produce collagen, the protein that gives skin elasticity and mechanical strength.

Of course the compatibility of the cells needs to be ascertained before printing the skin.3D-printed skin designed to be transplanted needs to be made from the patient's own cells, so their body doesn’t reject it.


Alfredo Brisac, the CEO of the bioengineering firm in charge of the research said that “This method of bioprinting allows skin to be generated in a standardized, automated way, and the process is less expensive than manual production.”
Meanwhile, for industrial uses such as chemical testing, the skin can be mass-produced from a batch of cells.

The plans to commercialise this research for the purpose of making life good is already underway.
