Levels of exosomes in urine of hypertensive patients. (A) There were no differences among the groups in percent of urinary PL-VAP+/CD31+, PL-VAP+/CD144+, and PL-VAP+/CD31+/CD144+ exosomes. (B) PTC-EMPs were identified using flow cytometry as PL-VAP+/CD31−/CD144− as shown in representative fluorescent images. Scale bar =20 µm. (C) Renal vein and systemic levels of PL-VAP+/CD31−/CD144− EMPs were not different among the groups, whereas their urinary levels were elevated in both EH and RVH compared to HVs (p<0.001 and p=0.001, respectively). EMPs, endothelial microparticles; HVs, healthy volunteers; EH, essential hypertension; RVH; renovascular hypertension *p <0.05 versus HV
