Figure 2: Migration of HUVECs by wound scratch test. HUVECs, human umbilical vein endothelial cells; LZDMS, long-zhi decoction medicated serum. (a, b) Control group: HUVECs scratch wound microscopic images at 0 h and 24 h. (c, d) The migrated distance of blank serum had no significant difference compared with the normal control group after 24 h. (e, f) H2O2 intervened HUVECs scratch wound at 0 h and 24 h. (g, h) The migrated distance of H2O2 with LZD-medicated serum treated HUVECs was much higher than H2O2, and LZD-medicated serum improved the migration of HUVECs. All experiments were performed in three replicates. versus the control; versus the control; , versus the H2O2 group.
