Storage time matters less than the quality of freezing, uninterrupted temperature control and documentation. For adipose SVF specifically, long-term data are limited, so ask the bank for its own thaw-viability results.","detailed_answer":null,"format":"paragraph","confidence":85,"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"},{"id":26,"title":"Effects of Cryopreservation on Stromal Vascular Fraction Viability in Human Adipose Tissue: Insights from a Systematic Review","url":"https://pubmed.ncbi.nlm.nih.gov/42631789/","publisher":"Tissue Engineering and Regenerative Medicine (2026)","type":"academic","accessed_at":"2026-09-14 13:42:07"}],"published_at":"2026-09-14 13:42:07"}
