CD151 and cancer: On the other hand, exosomes carry information not onlyin the form of genetic material but also in their protein content.Therefore, membrane proteins of exosomes (ExoMPs) are easy-to-reachpotential biomarkers.10 Tetraspanins suchas CD9, CD36, CD44, CD63, CD81, and CD151 are membrane proteins foundin exosomes and are investigated as potential biomarkers for varioustypes of cancer.
