Preclinical testing of Active Pharmaceutical Ingredients (API) is an important step in the evaluation of a future medicinal product. 3D bioprinting of systems that mirror organ function offers an ethical alternative to animal testing. Our specialists can 3D print a vascularised model of the pancreas with cells and a model neoplasm. It will be connected to a proprietary bioreactor with controlled parameters that reproduce physiological conditions. In terms of time and cost, it offers an interesting opportunity to evaluate the agreed impact parameters of the tested API on a custom 3D model of the organ.
