Nature Outlook: Extracellular RNA
RNA—the molecule best known for its part in translating genetic code into protein-making instructions—is finding a new role in medicine. Key to this is that microRNA, once thought to exist only in cells, has been shown to travel outside cells to tissues all over the body through the blood under the protection of “extracellular vesicles.” Scientists are studying the biomedical potential of extracellular RNA, particularly for detecting and treating disease
