Scientists Develop Human Skin That Can Be Printed In Under a Minute

The manufactured skin could become a solution to animal testing.

Scientists have discovered how to print human skin—and it takes less than a minute.
 
DeNova Sciences, a Singapore-based startup, developed a method of creating in-vitro skin that has the same chemical and biological properties as human skin. Their goal was to produce an alternative to animal testing.
 
“We can see that the industry is moving towards animal-free testing, so we really want to offer a solution to testing on the skin without using you know, animals or human skin,” DeNova Sciences Lab Manager John Koh explained.
 
The project is a collaboration with Singapore’s Nanyang Technological University. The synthetic skin is made from donated skin cells and collagen, which is printed in patterned layers—just like human skin. According to Reuters, each tiny piece of skin takes less than a minute to print, which is the distinctive quality of the project.
 
The pieces are then incubated for about two weeks, causing the skin cells to multiply and gain opacity. They can then be used to test the toxicity or irritability of a product—something that many companies usually rely on animal testing to determine.
 
DeNova Sciences says the skin will soon be used to test the effects of skin-whitening products.
