GPC1 and neoplasm: Immune lipoplex nanoparticle biochip assay showed GPC1 membrane protein expression in the microvesicle‐rich EV subpopulation, especially the tumor‐associated microvesicles, and Glypican1 (GPC1) mRNA expression in the exosomes‐rich (Exo)EV subpopulation served as a viable biomarker for PDAC [132].
