The novel 3D tumor microenvironment model was developed by the scientists Prof. Dr. Michael Außerlechner, Dipl. Ing. Dr. Judith Hagenbuchner and Daniel Nothdurfter in the 3D bio-printing laboratory of the Medical University of Innsbruck. The human cells of the model grow in a hydrogel in a microfluidic system made of plastic. The researchers are able to create fine capillaries similar to blood vessels with the bio-printer, so that all cells in the tissue model can be supplied with sufficient oxygen, nutrients and, if necessary, a drug.
