Effect of mechanical and hypotonic stimuli on ATP release from freshly isolated acinar cells and AR42J cells with/without dexamethasone. a and b ATP release in response to a mechanical stimulus induced by a pump injection of 50 μl of physiological saline solution at 260 μl/s into 100 μl of acinar (a) or AR42J (b) cell suspensions (n = 4–5). c and d Effect of pump injection speed on ATP release from pancreatic acini (c) or AR42J (d) (n = 4–5). e and f ATP release in response to addition of MilliQ water (33 % dilution) in acini (e) and AR42J cells (f)
