abstract：:In recent years, there has been exponential growth in the interest in microvesicles, which is reflected by the number of publications. Initially referred to as "platelet dust" by Peter Wolf in 1967, platelet microvesicles (PMV) are now recognized as important mediators of intercellular communication. There are example...
