A biobank and database system for storage of and interactions with biological samples in vitro is disclosed. The system comprises incubators for living tissue, and a number of biological samples where each biological sample is either an organoid or a sample containing live tissue, supported by or containing cellulose derived from tunicates. The system further comprises means for monitoring and manipulating each biological sample, a chronologic ledger with automatic registration of all relevant data pertaining to provenance and pre-history of each biological sample as well as information on all manipulations performed on each biological sample and results obtained. The system further comprises one or more nodes arranged to communicate with the incubators, and control access to the chronologic ledger and to the biological samples in the incubators. The chronologic ledger may be structured as a blockchain.
