Fig. 6. Changes in the cytosolic Ca²⁺ mobilisation of pancreatic acinar cells in response to perfusion with FCCP (0.5 µmol l^-1), followed by tBHP (1 mmol l^-1) in the presence of (A) 2-aminoethoxydiphenylborane (2-APB, 30 µmol l^-1) or (B) ryanodine (50 µmol l^-1). All experiments were performed in a Ca²⁺-free solution (1 mmol l^-1 EGTA was added). Traces are representative of 37 and 46 cells taken from 2 and 3 different experiments, respectively. (C) Histogram of the mean post-stimulus [Ca²⁺]_c under different experimental conditions of 2-3 independent experiments. Values are means ± s.e.m. ^*P<0.05.
