Respuesta :
Circulating extracellular vesicles (EVs) and cell-free RNA (cfRNA) are promising biomarkers for early cancer detection.
EVs are a heterogeneous combination of vesicles released from cells2,3,4,5 that are different in size and composition. EVs have cell-specific antigens on their surface that can be antibody tagged for imaging and/or isolation in -omics analyses6 because they are either generated from the plasma membrane or entail multivesicular endosome fusion with the cell surface.
EVs may carry a variety of proteins and nucleic acids, including being a possible carrier of cfRNA, according to mounting evidence9,10. Plasma contains protein-coding mRNA molecules known as cell-free messenger RNAs (cf-mRNA), which may be used as biomarkers11,12. The combination of these analytes for blood processing and storage is of great interest because EVs may transport a variety of extracellular RNAs, including cf-mRNA.
