Abstract

This video describes the technique used for isolating pancreatic acinar cells–exocrine cells–containing a variety of digestive enzymes. Primary acinar cells are useful in the ex vivo study of acinar-to-ductal metaplasia (ADM)–an early event in developing pancreatic cancer.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the jove veterinary review board. 1. Acinar Cell Isolation Sacrifice the mouse via CO2 induction, and perform cervical dislocation. Immediately dissect the pancreas. To dissect the pancreas, first pin the paws of the mouse to the polystyrene lid, orient the mouse such that the tail is facing the researcher, and s…
