Reproducible in-vitro canine skin has been grown in a laboratory setting for the first time by researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB. The research team developed a full-thickness dog skin equivalent based on native skin cells. This makes it possible to precisely test medical treatments in vitro on the sensitive skin of dogs. The skin equivalent can even be used to test the compatibility of care products such as shampoo or soap – eliminating the need for animal testing.
