Similar findings were obtained for the FASN+/CD63+ EV population in anaplastic astrocytoma patients (mean 2.9 × 105/mL AA vs 5.8 × 104/mL HD, P = 0.005) as well as for the FASN+/CD81+ EV population (mean 5.2 × 105/mL AA vs 2.3 × 105/mL HD, P = 0.03), (Figure 4C). This evidence concerns the gene CD63 and anaplastic astrocytoma.
