Figure 5

Peak amplitude of [Ca2+]i response of myoblasts and myotubes to caffeine and CPA. Bar diagrams summarize the response of the cell types shown in Figure 4. (a) myoblasts (+/+); (b) myotubes (+/+); (c) myoblasts (βˆ’/βˆ’): application of 20 mM caffeine followed by 10  πœ‡ M CPA; (d) myotubes (βˆ’/βˆ’):  2 successive applications of 20 mM caffeine followed by 10  πœ‡ M CPA. The number of cells tested is given in brackets.
