Autologous Fat Grafting Enhanced with Stromal Vascular Fraction (SVF) for Soft Tissue Reconstruction
Abstract
Autologous fat grafting continues to face a persistent challenge: retention rates that fluctuate unpredictably
between 20% and 80%. The stromal vascular fraction (SVF)—a heterogeneous cell population containing
adipose-derived stem cells and other regenerative cell types—has emerged as a promising adjunct. By
romoting angiogenesis and supporting tissue regeneration, SVF enhances graft survival [1,2].
This review examines current evidence on the mechanisms of SVF-enhanced fat grafting, the techniques used
for its isolation, and the clinical contexts in which it has been successfully applied [3]. Literature published
between 2015 and 2025 was analyzed, focusing on studies that investigated SVF-enriched fat grafting in
reconstructive surgery [4]. Evidence indicates that enrichment with SVF im proves graft retention, with rates
rising to 65–80% compared to 40–65% achieved with conventional methods. Enhanced neovascularization has
also been consistently reported [5,6]. Clinically, surgeons are applying SVF-assisted grafting in breastreconstruction, rehabilitation of radiation-damaged tissue, chronic wound management, and facial rejuvenation [7,8]. Both enzymatic digestion and mechanical separation techniques have proven effective for isolating SVF, offering flexibility depending on available resources and regulatory considerations [9,10]. Overall, SVF-enhanced fat grafting represents a significant advance in regenerative surgery. Multiple studies confirm its safety and therapeutic value, underscoring its potential to improve outcomes across a range of reconstructive and aesthetic applications [11,12].
