CAS, semantically Cell Alive System has been originated and developed by ABI. Co, Japan. CAS technology has brought about the innovation of food storage. Even after frozen, the food keeps the fresh flavor and taste. The mechanism is thought that freezing in the magnetic field prevents the microstructure from cryodamages, probably caused by ice crystal formation. Long-term storage with fresh taste enables to distribute delicious but delicate foods that had been consumed only in local area to urban area, regardless of time and distance. In addition to providing a chance to taste rare foods, CAS contributes to revitalization of local communities. As a next step, application of CAS for medical resources, i. e., cryopreservation of organs, tissues, and cells for transplantation is being undertaken. The project has started by cryopreservation of extracted wisdom teeth by Dr. T. Kawada and monkey ovaries by Dr. T. Sankai；teeth bank has been established and stored teeth may be implanted instead of lost teeth. Ovarial transplantation is hoped that the patients who has to be gonadectomized by medical reason leave the possibility of giving birth to own babies. And also,human hepatocytes that are cryopreserved for cell transplantation is being challenged by Dr. S.Enosawa. Relatively large amount of cells for the transplantation are frozen well by CAS system.
