Figure 9

Confocal planar slice image of uncoated control islets incubated in FITC-PEG5000-MDT (A); islet coated with 6 layers of PAMAM 15/20 and hyperbranched alginate-N3, followed by incubation with FITC-PEG5000-CH3 (B); and islet coated with 6 layers of PAMAM 15/20 and hyperbranched alginate-N3, followed by incubation with FITC-PEG5000-MDT (C). Scale bar = 50 μm.
