Positive correlations were also observed between serum-derived platelet associated EV CD42a (r = 0.32, p = 0.4, n = 8) and CD62P (r = 0.23, p = 0.5, n = 8), CD69 (r = 0.45, p = 0.2, n = 8) with IC leukemic cells in AML, ALL and CLL samples (Fig. 6b), even though not significant. The gene discussed is CD69; the disease is acute lymphoblastic leukemia.
