Scientist makes 3D-printed human skin to help end animal testing
Young Brazilian scientist Carolina Catarino has been awarded one of eight young researcher prizes of £10,000 ($13,250) by the Lush cosmetics company for her work on lab-grown human skin models. The skin models are made with 3D printing techniques and it is hoped they will make animal testing unnecessary. In future research, Catarino aims to increase the number of molecules in the skin models, add proteins for skin maintenance and introduce blood vessels for regenerative medicine testing and skin grafts. She is also working towards adding hair follicles, which would help show how substances can enter the body.
