The scientists at the Fraunhofer Institute hope the [[skin]] they’ve been able to produce will provide a 'humane alternative to using animals' in testing of cosmetics and other products.
After the cells from the [[Foreskin| foreskins ]] have multiplied inside the machine, they’re injected into a gel that forces them to grow into a sheet that simulates the epidermis — the outermost layer of human [[skin]]. To create a model that simulates human [[skin]], three of these layers are fused together.
The process of growing new [[skin]] takes about six weeks. At present, the Fraunhofer Institute is producing about 5,000 new samples per month.<ref>{{REFweb
