Figure 4. Modification of HA influences CD44 adhesion to HA hydrogels.

Figure 4.

Hydrogels were fabricated from modified HA macromers and characterized using (a) atomic force microscopy with CD44 modified beads for (b) quantification of adhesion forces (red: NorHA1, green: NorHA2, blue: MeHA). n ≥ 40 indentations across 3 hydrogels per group, dotted lines represent PEG hydrogel controls, * P < 0.05; ** P < 0.01; ## P< 0.01 relative to the PEG hydrogel control.
