The efficiency of human fat products in wound healing: A systematic review and meta-analysis
Xiao Y., Nie M., Xu W., Wu D.
Pooled 21 RCTs of autologous fat, SVF or ADSCs, finding faster healing rate, shorter healing time and more complete healing versus conventional treatment.

What was studied
Efficacy and safety of fat-derived products (including SVF) in wounds, especially refractory chronic wounds.
Methods
- • Systematic review and meta-analysis restricted to RCTs, stratified by fat product type.
Key findings
- • Healing rate and completeness were significantly better than conventional care.
- • Histology indicated increased epithelialization, collagen deposition and vascularization.
- • Reported adverse events were within an acceptable range.
Limitations
- • Pooled several fat product types, making the SVF-specific effect hard to isolate.
- • Wound types and baseline standard of care differed.
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • Limited follow-up cannot indicate long-term outcomes.
Clinical interpretation
Chronic wounds are among the most consistently supported indications for fat-derived products.
