3D Printed Human Skin Could Help End Animal Testing

Carolina Catarino, a Brazilian scientist whose trials utilize 3D printed skin to advance cruelty-free research, just won the 2017 Lush Prize awarded for innovations in the fight against animal testing.

Traditional animal tests begin with a piece of an animal, but the cells aren’t as complex as human skin cells, so Catarino’s goal is to create a more accurate model of human skin. She is also adding proteins (which sustain the skin), multiplying the cell quantity to observe how sunlight affects them, and increasing blood vessels that will help create skin grafts and can be utilized for regenerative medicine.
