摘要

Extracellular vesicles present a promising alternative to stem cells in regenerative medicine and gerontology. They offer significant advantages over cell transplantation, demonstrating potential for slowing aging and treating age-related diseases. Extracellular vesicles secreted by diverse cell types modulate inflammation, stimulate tissue regeneration, and exhibit anti-inflammatory and immunomodulatory properties. This work explores the therapeutic potential of extracellular vesicles as alternatives to cell therapy, examining their key advantages and current limitations. It specifically focuses on their roles within established aging mechanisms and their dual utility as biomarkers and therapeutic agents. Critical aspects of extracellular vesicle translation are addressed, including standardized methods for production, storage stability optimization, and engineering strategies for cargo loading and targeting. Extracellular vesicles possess unique biological properties—inherent biocompatibility, low immunogenicity, ability to cross biological barriers, and high biological activity at low doses. Preclinical studies across various age-related pathologies (neurodegeneration, cardiovascular disease, sarcopenia) consistently report efficacy in reducing inflammation, promoting tissue repair, and improving functional outcomes. These findings strongly support the capacity of extracellular vesicles to mimic many therapeutic effects of parental cells while mitigating risks like tumorigenicity or immunorejection associated with whole-cell therapies. Overcoming challenges in scalable manufacturing, quality control, regulatory standardization, and targeted delivery is essential for the clinical translation of extracellular vesicles. Despite these hurdles, their compelling preclinical evidence and inherent advantages position them as a major future direction. They are expected to play a key role in combating age-related decline and advancing regenerative medicine, becoming a cornerstone of next-generation biomedical interventions over the next decade.
