Exosomes are specifically secreted vesicles from living cells, responsible for intercellular communication and playing a critical role in immune systems. Since exosomes composed of numerous RNA, proteins, lipids, cytokines, several large-scale analysis such as proteomics and transcriptomics can often be performed. These vesicles also show potential for cancer diagnostics and determination of other diseases because they transport molecular contents of cells from which they originate. Learn more: exosome assay
