# SVF-assisted Fat Grafting

SVF-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.

## Key facts

- **First clinical description**: Yoshimura 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 [3]
- **Original procedure**: About 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 [3]
- **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% [4]
- **Efficacy by site**: Face showed a significant benefit (SMD 2.95); breast reconstruction showed no significant advantage (SMD 0.47); no benefit with water-assisted lipotransfer harvesting [4]
- **Methodological quality**: About 62% of included studies rated weak overall; mean follow-up 16.2 months, too short for oncologic conclusions [4]
- **Comparative study without benefit**: Peltoniemi 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 [5]
- **Breast-surgery evidence base**: 11 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) [6]
- **Reported complications (breast)**: Calcifications were the most frequently reported complication; none reported as malignant [6]
- **Preclinical and early clinical findings**: 16 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 [7]
- **Applicable US FDA guidance**: Final guidance 'Regulatory Considerations for HCT/Ps: Minimal Manipulation and Homologous Use', July 2020 (supersedes November 2017 version) [8]
- **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 [9]
- **Also called**: Cell-assisted lipotransfer (CAL) [1]
- **Evidence**: A 2024 systematic review assessed the efficacy of cell-assisted lipotransfer; a 2021 study compared CAL with PRP-assisted lipotransfer [1]
- **Proposed mechanism**: Stromal cells may support angiogenesis and graft survival (hypothesis under study) [2]

## Overview

Part of the liposuctioned fat is processed into SVF, which is mixed with the remaining fat before injection. Systematic reviews of cell-assisted lipotransfer report generally higher retention than conventional grafting in pooled analyses, but study quality, cell dose and measurement methods vary, and regulatory status of SVF processing differs by country. It is not a stem cell therapy in the sense of culture-expanded cells.
