Abstract (original English)
Cell-free fat extract (CEFFE), an adipose-derived biologic, offers a potent alternative to cell-based therapies by delivering a complex milieu of growth factors (e.g., VEGF, EGF, and BDNF) and regulatory proteins without the tumorigenic, immunogenic, or ethical challenges associated with stem cell applications. The objective of this study is to systematically evaluate CEFFE's regenerative efficacy across diverse tissue systems-including musculoskeletal, neural, reproductive, dermal, ocular, and systemic applications-while synthesizing its underlying molecular mechanisms, clinical outcomes, and translational challenges. A comprehensive literature review was conducted utilizing databases such as PubMed, Scopus, and Web of Science, focusing on preclinical and clinical studies published from January 2018 to May 2026. Over 55 articles were analyzed to evaluate CEFFE's efficacy, dosage-response patterns, and molecular pathways. CEFFE accelerates tissue repair through three conserved mechanistic axes: antiapoptotic survival (e.g., PI3K-Akt/mTOR activation and NRF2-mediated antiferroptosis), context-specific immunomodulation (e.g., Annexin A5-mediated M2 macrophage polarization and NLRP3 inflammasome disruption), and extracellular matrix remodeling alongside angiogenesis (e.g., TGF-β/Smad signaling). Emerging evidence highlights CEFFE's efficacy in novel domains such as intervertebral
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
Evidence level
Several human studies exist, but sample sizes, methodology, or follow-up remain limited, so conclusions are not firm.
