The role of ERK in AGE-induced angiogenesis. HUVECs were pretreated with 20 μmol/L PD98059 for 30 min and then incubated with 100 μg/mL AGEs for 24 h. CCK-8 was used to evaluate the proliferation of HUVECs (A), scratch wound healing (B) and transwell migration assay (C) were used to measure the migration of HUVECs. The tube length, numbers of branch points, and vessel area were observed in Matrigel medium (D). n ≥ 4 independent experiments. P < 0.05 versus control, #P < 0.05 versus AGEs.
