Long-Zhi Decoction Medicated Serum Promotes Angiogenesis in Human Umbilical Vein Endothelial Cells Based on Autophagy

Figure 4

The production of autophagosomes. HUVECs, human umbilical vein endothelial cells; LZDMS, long-zhi decoction medicated serum. (a/b) Cells were treated with or without blank serum for 24 h, and autophagosomes were not detected by TEM. (c) Cells were treated with H₂O₂ (400 μmoLL⁻¹) for 24 h, and a small amount of autophagosomes was detected by TEM. (d) Cells were treated with H₂O₂ + LZD-medicated serum for 24 h, and more autophagosomes were detected by TEM.
