Expression of glucagon and somatostatin (SOM) in MDFs derived islet-like clusters. Islet-like clusters derived from Clone 27 and 45 after 14 days of pancreatic induction were positive for anti-Glucagon (A) and anti-SOM (B) staining (red), but negative in Clone 46. Nuclei were stained with DAPI (blue). Scale bars, 100 μm.
