Glycosaminoglycan (GAG) Production and Cell Activity A GAG/DNA content B Cell activity normalized to the DNA content. The activity was different for all the loading groups and the control groups. For the loading group loaded with a high cyclic regime the relative cell activity is lowest, however, not statistically significant. For d0 and unloaded control: n=4; loading groups: n = 8. All values indicated as mean ± SD.
