مفهوم
Stem Cell Fat GraftingA consumer and marketing term used for fat grafting that is enriched with cells isolated from adipose tissue. It is not a standardised academic term and does not denote culture-expanded stem cell therapy.تاريخ التحديث 21 سبتمبر 2026طبي
SVF-assisted Fat GraftingSVF-assisted fat grafting (a form of cell-assisted lipotransfer) enriches the fat graft with stromal vascular fraction isolated from part of the harvested fat, with the aim of improving graft survival.تاريخ التحديث 21 سبتمبر 2026العلاقة بينهماStem Cell Fat Grafting — يشير عادةً إلى → SVF-assisted Fat Grafting

SVF-assisted Fat Grafting
First clinical descriptionYoshimura K et al., 'Cell-assisted lipotransfer for cosmetic breast augmentation', Aesthetic Plast Surg 2008;32(1):48–55; 40 women, maximum follow-up 42 months
Original procedureAbout half of the aspirated fat is processed to isolate fresh SVF, which is recombined with the other half before injection; the fat acts as a living scaffold
Pooled fat survival (2026 meta-analysis)72.78% with enrichment vs 45.28% conventional (SMD 2.44; 95% CI 1.00–3.88); 15 studies, 634 patients; heterogeneity I² = 97.19%
Efficacy by siteFace showed a significant benefit (SMD 2.95); breast reconstruction showed no significant advantage (SMD 0.47); no benefit with water-assisted lipotransfer harvesting
Methodological qualityAbout 62% of included studies rated weak overall; mean follow-up 16.2 months, too short for oncologic conclusions
Comparative study without benefitPeltoniemi et al. 2013 (JPRAS 66:1494–1503): 18 women, MRI at 6 months; graft survival 50% with Celution SVF enrichment vs 54% without, difference not significant
Breast-surgery evidence base11 studies, 336 patients, follow-up 6–42 months; 8 of 11 studies had no control group; only one used a validated patient-reported outcome measure (BREAST-Q)
Reported complications (breast)Calcifications were the most frequently reported complication; none reported as malignant
Preclinical and early clinical findings16 of 18 preclinical studies showed significantly improved retention (1.19- to 4.14-fold); 6 of 7 clinical studies favored CAL; evidence judged low quality
Applicable US FDA guidanceFinal guidance 'Regulatory Considerations for HCT/Ps: Minimal Manipulation and Homologous Use', July 2020 (supersedes November 2017 version)
Enzymatic SVF isolation (US)Collagenase digestion to isolate SVF falls outside 'minimal manipulation'; non-enzymatic mechanical point-of-care methods are proposed as possible alternatives
Also calledCell-assisted lipotransfer (CAL)
EvidenceA 2024 systematic review assessed the efficacy of cell-assisted lipotransfer; a 2021 study compared CAL with PRP-assisted lipotransfer
Proposed mechanismStromal cells may support angiogenesis and graft survival (hypothesis under study)
