used in industry. A new type of scaffold was developed based on inverted colloidal crystal (ICC) topology, which can resolve these issues and result in adequate
ex vivo models with 3D cellular organization resembling that of original organs. Additionally, the ICC scaffolds can be standardized exceptionally well,
which is critical for reproducibility of the drug screening assays. The ex vivo replicas of liver and bone marrow made in well plate format adaptable for drug
screening will be demonstrated.
