Researchers from Nagasaki University in Japan are working on scaffold-free approaches for an artificial trachea by assessing the circumferential tracheal replacement using scaffold-free trachea-like grafts, generated from isolated cells in an inbred animal model. Regenova 3D bioprinter from Cyfuse Biomedical was used to assemble multicellular spheroids in a tube-shaped artificial trachea.
