Figure 1

Selective binding and retention of FGF2 to ~1 mm diameter CS-GAG matrix surrounded by HA matrix. (A) Bright-field image of the interface (indicated by white dotted line) of the CS-GAG and HA matrices. (B) Wisteria f loribunda (WFA) agglutinin labeling (pseudocolored yellow) of CS-GAG matrix. (C) Area of FGF2 binding and retention (pseudocolored red); (D) Overlay of WFA and FGF2 labeling demonstrating the preferential FGF2 binding and retention in the CS-GAG matrix when compared to surrounding HA matrix. Scale = 100 μm.
