(a) DNA content analysis of the different groups using the picogreen assay measured at 0 and 7 days. Please note the decrease in DNA content for all of the groups after 7 days of culture. Values are reported as mean ± standard deviation, n = 4. (@) represents statistically significant difference from the control group at that time point and (*) represents statistically significant difference from hanging drop (t = 0) time point (p < 0.05). There was no significant difference in values between the coated and non-coated groups.
