Liver progenitor cells (red) form a toroid shaped organoid around a PEG acrylate pillar. Portal fibroblasts (green) are encapsulated in the pillar to create a spatially organized co-culture for modeling bile duct development. This image was taken at IGB using the LSM 880 and reconstructed using IMARIS.
