Photo documentary on bioprinting. Zurich University of Applied Sciences (ZHAW) is working with a bioprinter from regenHU to produce different human tissues. Bioprinting allows three dimensional tissue production in a fast and controlled manner by the precise positioning of primary cells, biomaterials and growth factors. Thereby, bioprinted tissues simulate the complex in vivo situation of our body. Tissues are produced in a layer by layer mode by alternating photopolymerized bioink and cells. Before using for substance testing the tissue are matured in a cell culture environment. In future, printed tissues could reduce animal experiments in drug development and foster regenerative medicine. The coloration show the viability of fibroplasts after two days.
