Figure 2. Viability of HPDL fibroblasts treated with AGE-BSA, BSA and control for 24, 48, and 72 h. Pooled analysis indicated significant differences in viability at 24, 48, and 72 h in group A (*P<0.05), and significant differences between group A and group C (**P<0.01), but no significant difference in the viability of group B and group C at any time (P>0.05). One-way ANOVA was used for statistical analyses.
