Abstract (original English)

Background Bone healing following pathology or surgery is a complex, multiphase process involving coordinated cellular and molecular activities. Various stimulation strategies have been used to enhance bone repair. Recently, stromal vascular fraction (SVF)-a heterogeneous, adipose-derived cell mixture containing pericytes, smooth muscle cells, and adipose-derived stem cells with regenerative, immunomodulatory, and angiogenic properties-has been explored in clinical settings to promote accelerated bone regeneration. Methods Following the PRISMA guidelines, a systematic search was conducted in PubMed, Embase, and Web of Science. Eligible studies were English-language clinical investigations involving patients with bone defects treated with SVF, either alone or combined with other interventions, reporting outcomes related to bone repair. Results Ten clinical studies (5 case reports, 4 prospective cohorts, and one randomized clinical trial) involving 214 patients (46.3% male) were included. Radiologic and histologic assessments consistently showed enhanced bone regeneration in SVF-treated sites, including increased ossification, bone volume, mineral content, and defect closure. Quantitative comparisons, where available, favored SVF in bone dimensions, fusion rates, and implant success. Stromal vascular fraction therapy was well tolerated, with no serious adverse events and only min
