FOLH1 and ovarian carcinoma: Nonetheless, tissue-specific EVs can be isolated from blood plasma by immunocapturing, using specific antibodies recognizing EV surface molecules, such as NCAM or L1CAM for neural cell-derived EVs [6,21,22], EpCAM for epithelial cells including breast or ovarian cancer-derived EVs [23], or prostate-specific membrane antigen (PSMA) for prostate cell-derived EVs [24,25].
