Time course of release of 70 kDa (A) and 2000 kDa (B) fluorescein-conjugated dextran from 1, 2, and 5% MeHA hydrogels (normalized to maximum concentration from 1% MeHA for a given dextran molecular weight). Effective diffusivity (C) of dextran of both sizes decreased with increasing MeHA macromer concentration. (n=3/group; ** indicates p<0.05 vs. both 2% and 5% MeHA groups; * indicates p<0.05 vs. the 5% MeHA group only)
