Glycosaminoglycan content and compressive stiffness of self-assembled constructs. (A) GAG/WW for all groups. Ribose treatment during Week 2 and All Weeks had the greatest GAG/WW (34% and 35% > control, respectively). Week 1 had the least GAG/WW (18% < control). (B) Compressive stiffness for all groups. The highest aggregate moduli were found in All Weeks (62% > control), followed by Week 2 (40% > control). Week 1 had the lowest aggregate moduli (54% < control). As expected, trends for aggregate moduli followed GAG/WW trends. Data are presented as means ± standard deviations. Groups not connected by the same letter are significantly different (p<0.05).
