Autologous fat comes from the same person, so it carries no risk of immune rejection and no allergy or viral-transmission concerns. Some of the graft is still usually lost, because transferred fat has no blood supply at first and fat cells far from nearby tissue can die before new vessels form. Reviews report resorption of 25% to 80%, depending on technique and the recipient site.","detailed_answer":"<p>Graft loss comes from lack of oxygen, not rejection. Experimental work shows that fat cells near the edge of a graft survive, while cells in the centre can die. Stromal cells in a middle zone can replace some of the dead fat cells.</p>","format":"paragraph","confidence":75,"verified_at":"2026-09-18 06:21:20","updated_at":"2026-09-18 15:21:20"},"sources":[{"id":11,"title":"NCI Dictionary of Cancer Terms: autologous","url":"https://www.cancer.gov/publications/dictionaries/cancer-terms/def/autologous","publisher":"National Cancer Institute (NCI)","type":"government","accessed_at":"2026-09-19 18:01:04"},{"id":125,"title":"Autologous Fat Grafting in Plastic and Reconstructive Surgery: An Historical Perspective (Costanzo D, Romeo A, Marena F; Eplasty 22:e4)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC9350545/","publisher":"Eplasty / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:41"},{"id":126,"title":"The fate of adipocytes after nonvascularized fat grafting: evidence of early death and replacement of adipocytes (Eto H et al.; Plast Reconstr Surg 129(5):1081-1092)","url":"https://pure.teikyo.jp/en/publications/the-fate-of-adipocytes-after-nonvascularized-fat-grafting-evidenc/","publisher":"Plastic and Reconstructive Surgery (Teikyo University research portal)","type":"academic","accessed_at":"2026-09-19 18:01:42"},{"id":127,"title":"Application of adipose-derived stromal cells in fat grafting: Basic science and literature review (Moustaki M et al.; Exp Ther Med 14(3):2415-2423)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC5609216/","publisher":"Experimental and Therapeutic Medicine / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:42"},{"id":128,"title":"Fat Ful'fill'ment: A Review of Autologous Fat Grafting (Marwah M et al.; J Cutan Aesthet Surg 6(3):132-138)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC3800286/","publisher":"Journal of Cutaneous and Aesthetic Surgery / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:42"},{"id":129,"title":"A Systematic Review of the Literature and Meta-Analysis of Autologous Fat Transfer: Fat Transfer Confers a 4.2% Incidence of Complications (Bechar et al.)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC12622863/","publisher":"Cureus / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:43"},{"id":130,"title":"Impact of donor site on fat graft survival in autologous fat transfer to the breast: A systematic review (Goeree et al.)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC13382271/","publisher":"JPRAS Open / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:43"},{"id":131,"title":"Report on Mortality from Gluteal Fat Grafting: Recommendations from the ASERF Task Force (Mofid MM et al.; Aesthet Surg J 37(7))","url":"https://www.theaestheticfoundation.org/research/funded-research/report-on-mortality-from-gluteal-fat-grafting-recommendations-from-the-aserf","publisher":"Aesthetic Surgery Education and Research Foundation","type":"organization","accessed_at":"2026-09-19 18:01:44"},{"id":132,"title":"Same Surgical Procedure Exception under 21 CFR 1271.15(b): Questions and Answers Regarding the Scope of the Exception","url":"https://www.fda.gov/regulatory-information/search-fda-guidance-documents/same-surgical-procedure-exception-under-21-cfr-127115b-questions-and-answers-regarding-scope","publisher":"US Food and Drug Administration (CBER)","type":"government","accessed_at":"2026-09-18 18:00:56"},{"id":133,"title":"Intraoperative Strategies for Minimal Manipulation of Autologous Adipose Tissue for Cell- and Tissue-Based Therapies: Concise Review (Trivisonno A et al.)","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC6877766/","publisher":"Stem Cells Translational Medicine / PubMed Central","type":"journal","accessed_at":"2026-09-19 18:01:44"}],"published_at":"2026-09-18 06:21:20"}
