Exosomes, a subtype of extracellular vesiclesExtracellular vesicles (EVsExtracellular vesicles), have received significant attention in clinical applications due to their potential in therapeutics and diagnostics across various medical fields. Exosomes are derived from cells and play a crucial role in intercellular communication by transferring bioactive molecules. They are involved in physiological processes such as immune response, tissue repair, and modulation of inflammatory responses. Exosomes can be biocompatible carriers that transport bioactive molecules to specific target cells. They have shown promise as potential therapeutic agents for various diseases, including cancer, neurodegenerative diseases, cardiovascular diseases, inflammatory diseases, osteoarthritis, lung diseases, liver diseases, fibrosis diseases, and rare genetic disorders. Exosome therapy is a promising but evolving field, requiring further research and clinical trials to fully understand its efficacy and safety. Large-scale production techniques and innovative preservation strategies are crucial for maintaining exosome stability and functionality. Future research aims to optimize these processes and explore engineered exosomesExosomes for targeted therapy. Moreover, exosomes are a promising tool for early diagnosis and treatment monitoring for diseases like cancer, Alzheimer’s, multiple sclerosis, myocardial infarction, and heart failure. Overall, exosomesExosomes represent a versatile and promising tool in regenerative medicine and precision therapy, with ongoing clinical trials exploring their full potential in various therapeutic contexts.
