Fig. 1From: Role of extracellular vesicles in tumour microenvironmentComposition and structure of extracellular vesicles (EVs). EVs is composed of a phospholipid bilayer surrounding protein (membrane protein and cargo protein) and nucleic acid. Membrane proteins include tetraspanins (CD9, CD63, CD81, etc), adhesion molecules (integrins, EpCAM, Ephrin, etc.), MHC, and receptors. Nucleic acid include DNA and RNA (mRNAs, miRNAs, LncRNAs, and circRNAs). Phospholipid bilayer provides protection to the cargo insideBack to article page
