Singapore scientists recently announced that they had developed a technology to print a human-sized piece of human skin in less than a minute.
DeNova Sciences Laboratory Director John Koh said: The product is made from donor skin and collagen. Therefore, this piece of skin has the same chemical and biological properties as human skin. DeNova Sciences is currently cooperating with Nanyang Technological University of Singapore to develop this product.
This is considered a major turning point in testing cosmetics and other non-animal products in the future.
In the context of an industry that tends to avoid animal testing, Singaporean scientists are eager to find a solution that allows them to be tested on skin without the need for animals or humans. As a result, the team has speeded up the manufacturing process through the use of printers to precisely place patterns like human skin. Each of these small pieces of leather takes less than a minute to print and is considered a highlight of the project.
The mixture is then incubated for 2 weeks as the skin cells multiply and become more and more opaque, like a white film. This skin patch can be used to test the level of toxicity or irritation from substances, as well as the permeability of active ingredients in products such as cosmetics.
The team is currently focusing on developing skin samples that have pigmentation similar to Asian skin cells to test the whitening effects of cosmetics.
The first infant to have a successful skin transplant in the world. Ja’bari Gray is under intensive care right after her birth on January 1, 2019 at Methodist Hospital in San Antonio. The baby weighs 1.37 kg and most of the body has no skin covering, only skin covering the head and face, unable to open eyes. I have to undergo many surgeries continuously to improve the condition of no skin on the body. I was the first infant to successfully have a skin transplant in the world.
