(A) Relative fluorescence intensity or representative images of autophagy activity by in vitro culture and chloroquine treatment. Autophagy activity was evaluated by DAPGreen staining or DAPGreen stained images after in vitro culture to morula embryo stage. 0 μM CQ (a); 1.0 µM CQ (b); 2.0 µM CQ (c); morula embryo stage. Embryos obtained by perfusion manipulation after in vitro culture until the mulberry embryo stage (d). Scale bar = 10 µm. (B) DAPGreen relative fluorescence intensity when the untreated area is set as 1. Data represent means ± SEM for each treatment group obtained from at least three independent replicates. Different letters represent significant differences (P < 0.05).
