Localisation of carboxylester lipase (CEL) in pancreatic acinar cells and lobules. (A) Light-transmitted and fluorescent images of acinar cells showing CEL (green) location in the apical granular region, surrounded by peri-granular mitochondria (mitochondrial peptidyl-prolyl cis-trans isomerase: red). Nuclei co-stained with Hoechst 33342 (blue). (B) Similar distribution of CEL in unstimulated intact tissue. Treatment with physiological cholecystokinin (10 pM for 30 min) caused CEL to redistribute into the lumen between acinar clusters suggestive of secretion. (C) A diffuse intragranular and extragranular (apical and basolateral) distribution of CEL was observed in intact pancreatic lobules obtained from mice treated with ethanol/POA combination to induce alcoholic acute pancreatitis (i.p. ethanol (1.35 g/kg) and POA (150 mg/kg)).
