Abstract (original English)

Adipose-derived stem cell exosomes (ADSC-Exos) have emerged as promising cell-free therapeutic agents in regenerative medicine, offering many benefits of stem cell therapy without the risks of cell transplantation. These nanoscale vesicles (30-150 nm) contain bioactive cargo including proteins, microRNAs, and lipids that mediate tissue repair through multiple mechanisms: promoting angiogenesis, modulating inflammation, reducing fibrosis, and activating endogenous regenerative pathways. Recent preclinical studies demonstrate remarkable efficacy across diverse applications, from accelerating chronic wound healing and stimulating skin regeneration to repairing cartilage, bone, and nerve tissues. In cardiovascular applications, ADSC-Exos protect against ischemic damage and improve cardiac function post-infarction. Neurologically, they show potential in stroke recovery, spinal cord injury, and neurodegenerative diseases by crossing the blood-brain barrier and delivering neuroprotective signals. Their potent immunomodulatory properties make them candidates for treating inflammatory and autoimmune conditions. Early clinical trials report encouraging safety profiles and preliminary efficacy in conditions ranging from acne scarring to Alzheimer's disease. However, significant challenges remain in standardizing isolation methods, ensuring consistent potency, scaling production to clinica
