Extracellular Vesicle miRNA Detection Using Molecular Beacons.

Many studies have recently focused on extracellular vesicles. Extracellular vesicles including exosomes are nanosized vesicles that are produced and secreted by cells. Extracellular vesicles contain various types of nucleic acid biomarkers, including microRNAs (miRNAs ) from their parent cells. As high concentrations of extracellular vesicles are found in most body fluids, miRNA detection of exosomes in body fluids, including blood and urine, enables early and easy disease diagnosis. In this context, the in situ detection method of extracellular vesicles miRNA using molecular beacons is described here.
