Abstract (original English)

Metabolic diseases, such as obesity, type 2 diabetes mellitus, non-alcoholic fatty liver disease, and atherosclerosis, represent a growing global health burden. Adipose-derived stem cells (ADSCs) have emerged as promising therapeutic agents due to their multipotency, paracrine activity, and potential for engineering targeted interventions. This review highlights recent advances in targeted ADSC strategies, focusing on their mechanisms, clinical applications, and translational challenges. Key targeted approaches include engineered exosomes for precise immunomodulation, surface-modified ADSCs for enhanced tissue homing, and biomaterial-based delivery systems for sustained and local release. Preclinical studies have demonstrated that these strategies can significantly improve glucose homeostasis, reduce hepatic steatosis, and alleviate chronic inflammation. However, clinical translation faces hurdles, including donor-dependent heterogeneity, a lack of standardized protocols, and insufficient long-term safety data. Future efforts should prioritize the development of precision-targeted ADSC therapies through genetic engineering, functionalized biomaterials, and rigorously controlled clinical trials to fully exploit their potential to treat metabolic diseases.BackgroundMetabolic diseases are prevalent worldwide, with conditions such as metabolic dysfunction-associated steatotic liver
