How can laboratory animals be dispensed with completely?
Many new methods have resulted in a large number of animal studies being replaced completely by test tube methods in recent years. Bayer, for example, was involved in the development of a laboratory test which detects whether the skin is made more sensitive to light by an active ingredient (a dangerous side effect of many substances). In this “3T3 NRU phototoxicity test”, skin cells are exposed to ultraviolet light in a Petri dish. The sensitivity of this test was recognized by the OECD in 2003. Previously, animal studies were required to research this effect. These are now completely redundant.
