miR-155 Promotes ox-LDL-Induced Autophagy in Human Umbilical Vein Endothelial Cells

Figure 1

TEM images of HUVECs. HUVECs were exposed to ox-LDL (100 μg/ml) for 6 h and 12 h, and cell samples were collected for TEM analysis. Autophagosomes were indicated by arrows. Autolysosomes were indicated by asterisks. N: nucleus. Scale bar = 500 nm.
