Effect of haem on HMEC-1 cell migration. a, Images of HMEC-1 cells were taken at 0 h and 24 h after scratching; the solid line indicates the edges of the wound at 0 h after scratching, and the dotted line indicates was the migration front of cells at 24 h after scratching (scale bar = 500 μm). b, Quantitative analysis of the HMEC-1 cell migration area. All data are presented as the means ± SD, and the experiment was repeated three times (n = 3). One-way ANOVA or multivariate ANOVA was performed
