FIG. 6.
DNA content in all the groups decreased during the 16-day period (A), while the 30.00 m/v gelatin group had the highest ratio of DNA/DNAday 0 at day 16 compared to the other two groups (B). Confocal imaging shows live and dead cells, which fluoresce green and red, respectively (C). The vast majority of cells were alive at day 0 in all the groups and all the groups appeared to have less cells stained green at day 16 relative to day 0. Scale bar is 100 μm. * indicates a statistical difference between groups (p<0.05). # indicates a statistical difference from the other two groups at a specific time point (p<0.05).
