Novel three-dimensional (3D) biofabrication platforms can allow magnetic 3D bioprinting (M3DB) by using magnetic nanoparticles to tag cells and then spatially arrange them in 3D around magnet dots. Here, we report an M3DB methodology to generate salivary gland-like epithelial organoids from stem cells. These organoids possess a neuronal network that responds to saliva neurostimulants.
