FIG. 12.

Macrophage percent of cell population from an in vivo subcutaneous model. Macrophage population was investigated by examining three standardized images from each of n=5 samples per treatment group. Macrophage fraction was defined as the number of cells determined to have F4/80 staining divided by the total cells counted per image in a blinded study. Data are presented as an average of each of these fractions, and error was calculated as the standard deviation between all images in each group. Population fractions from the GA-treated samples and the PPF reinforced samples are significantly different, as determined by a one-way ANOVA test, followed by a post hoc Tukey's test (p<0.05). Groups that share the same letter are not statistically different.
