Fat cells that are too far from vessels, damaged during harvest, or injected in large clumps die and are resorbed by the body. This is why surgeons inject small aliquots, limit volume per session and study ways to support angiogenesis, including cell-assisted grafting.","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":21,"title":"Advancing fat graft survival: from adipose-derived stem cell mechanisms to next-generation regenerative strategies","url":"https://pubmed.ncbi.nlm.nih.gov/42388980/","publisher":"Frontiers in Cell and Developmental Biology (2026)","type":"academic","accessed_at":"2026-09-14 13:42:07"},{"id":10,"title":"NCI Dictionary of Cancer Terms: angiogenesis","url":"https://www.cancer.gov/publications/dictionaries/cancer-terms/def/angiogenesis","publisher":"National Cancer Institute (NCI)","type":"government","accessed_at":"2026-09-14 13:42:07"}],"published_at":"2026-09-14 13:42:07"}
