Abstract (original English)

Stromal vascular fraction (SVF) therapy is a promising regenerative medicine strategy derived from adipose tissue, containing a heterogeneous mix of cells, including adipose-derived stem, endothelial, and immune cells. Despite its potential in treating conditions like osteoarthritis, chronic wounds, and myocardial ischemia, significant challenges impede its clinical translation. Key obstacles include biological variability in SVF composition, unclear mechanisms of action, regulatory ambiguities, and the technical difficulty of ensuring standardized and scalable isolation methods. Furthermore, patient-specific factors, ethical concerns, and the need for comprehensive efficacy assessment complicate clinical application. Addressing these challenges requires advancements in technology, regulatory flexibility, interdisciplinary collaboration, and personalized therapeutic approaches. Innovations such as automated isolation systems, advanced biomaterials, and CRISPR-based gene editing are potential solutions to improve the therapeutic reliability of SVF. A structured roadmap, including preclinical research, regulatory approval, and post-market surveillance, is proposed to advance SVF therapies from the laboratory to clinical practice. Future directions should focus on large-scale clinical trials, biomarker development, real-world evidence generation, and standardization of protocols t
