Made up of skin cells from donors and collagen, the in-vitro skin has the same chemical and biological properties as human skin, says John Koh, lab manager at start-up DeNova Sciences, which is collaborating with Singapore’s Nanyang Technological University on the product. Each tiny piece of skin takes less than a minute to print, which is the distinctive quality of this project. The mixture is then incubated for about two weeks, as the skin cells multiply and gain opacity, turning into a whitish membrane. A researcher holds a container of lab-made human skin before the samples are extracted at Nanyang Technological University in Singapore. His team is now focusing on developing skin that includes Asian pigment cells to test the whitening effects of cosmetics and skincare products.
