Cell adhesion on PCL films after 24 h. DAPI staining and quantification of HUVECs seeded on gelatin and on PCL films treated with water, NaOH, KOH, HMD, NaOH + HMD, and KOH + HMD. The cells were left to grow for 24 h n = 4-5. Representative images of each condition. Data are presented as mean ± SEM. Statistical significance was tested with one-way ANOVA. , . Scale bar: 50 μm.
