Figure 3

Fluorescence microscopic imaging of immunostaining for nestin, somatostatin, glucagon and C-peptide. The cells after 46 days of differentiation were stained with antibodies against nestin (red), somatostatin (red), glucagon (green) and C-peptide (red), followed by appropriate secondary antibodies conjugated to fluorochromes (blue, DAPI for nuclear staining; red, Cy-3; green, FITC). A merge of both images shows localization of nestin (A), somatostatin (B), glucagon (B,C), and C-peptide (C). The images were taken at magnifications of ×20 (A,B) and ×10 (C).
