Cells are mixed with a cryoprotectant, cooled in a controlled way and kept in liquid nitrogen. Some cells do not survive freezing and thawing, so viability is tested afterwards.","detailed_answer":null,"format":"paragraph","confidence":75,"verified_at":"2026-09-14 13:42:07","updated_at":"2026-09-14 22:42:08"},"sources":[{"id":9,"title":"NCI Dictionary of Cancer Terms: cryopreservation","url":"https://www.cancer.gov/publications/dictionaries/cancer-terms/def/cryopreservation","publisher":"National Cancer Institute (NCI)","type":"government","accessed_at":"2026-09-14 13:42:07"}],"published_at":"2026-09-14 13:42:07"}
