The neural precursor cell-specific marker nestin is expressed in fetal and adult pancreas, but its role is not fully understood. Using nestin-enhanced green fluorescent protein (EGFP) transgenic mice and fluorescence activated cell sorter, we characterized nestin-positive cells in adult mice pancreas. EGFP mRNA- and protein-positive cells expressed amylase, a pancreatic exocrine marker. Interestingly, EGFP mRNA-negative and protein-positive cells expressed insulin, glucagon, somatostatin and pancreatic polypeptide, pancreatic endocrine markers. These findings demonstrate that nestin-positive cells comprise a portion of pancreatic exocrine cells and suggest that they can be differentiated into pancreatic endocrine cells.
