Abstract (original English)

Adipose-derived cellular therapies, including stromal vascular fraction (SVF) and adipose-derived stem cells (ASCs), have demonstrated increasing therapeutic potential across regenerative medicine applications. This narrative review examines the current evidence supporting the use of SVF and ASCs in 2 primary clinical contexts: osteoarthritis (OA) and chronic wound healing. SVF, a heterogeneous cell population isolated from lipoaspirated fat via enzymatic or mechanical methods, and ASCs, a more homogeneous culture-expanded mesenchymal cell product, both exert regenerative effects through angiogenic, immunomodulatory, and reparative mechanisms. In OA, both cell types have been shown to significantly reduce pain and improve function, with some studies indicating cartilage regeneration on imaging. While ASCs may offer faster symptom relief due to higher purity and dosing, SVF remains a more accessible, minimally manipulated alternative with comparable long-term outcomes. In wound healing, adipose-derived therapies have been associated with accelerated closure of chronic ulcers through enhanced neovascularization, modulation of the inflammatory microenvironment, and promotion of granulation tissue and re-epithelialization. Across both indications, these therapies have shown a good safety profile, with minimal adverse events reported. The review also addresses regulatory distinction
