ND-DOX-loaded platelets maintained viability probably through induction of autophagy. (A) Microscopy of FDA staining of platelets loaded with ND-DOX or DOX. (B) Viability of platelets loaded with ND-DOX or DOX, assayed by CCK-8 test. (C–E) Western blot analysis of caspase-3, ATG5, Beclin-1 and LC-3 expression in platelets loaded with ND-DOX or DOX. (F) TEM observation of platelets loaded with ND-DOX (Plt@ND-DOX). White arrow marked was autophagosomes. Values were means ± SD (n = 3, * p < .05). Plt@ND-DOX refers to platelets loaded with ND-DOX.
