The contents of small extracellular vesicles. Almost all types of cells can secrete small extracellular vesicles, and small extracellular vesicles widely contain nucleic acids such as microRNA (miRNA), lncRNA, circRNA, mRNA, proteins, and lipids. Their surface markers mainly include CD63, CD81, CD9, ALG-2 Interacting protein X (Alix), tumor susceptibility gene 101 (TSG101), and heat shock protein 70 (HSP70)
