Cell survival on PCL films after 72 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 cultured for 72 h n = 5. Representative images of each condition. Data are presented as mean ± SEM. Statistical significance was tested with one-way ANOVA. , . Scale bar: 50 μm.
