Brinter is collaborating with the PeuhuLab, an academic research group from the University of Turku, Finland, in research related to breast development and cancer. The characteristics of ECM (collagen I, fibronectin, and Matrigel) and organotypic mammary gland differentiation or malignant growth are studied by 3D bioprinting of human mammary gland-like microenvironment. The study utilizes primary human mammary epithelial cells and control of the spatial location of the matrices and the matrix stiffness. Bioprinting with the Brinter® 3D bioprinter is expected to speed up breast cancer research significantly.
