Adenosine and AMP accumulation in the medium of non-stimulated and electrostimulated primary skeletal muscle cells: effect of NBMPR and AOPCP Muscle cells were incubated with medium alone (control) or in solution containing either NBMPR or AOPCP, or both. This was performed without electrostimulation (A and C, open symbols) or with electrostimulation (B and D, closed symbols). Values are mean ±s.e.m. of 6–17 cell dishes. *Significantly different from control value at same point in time: P < 0.05. †Significantly different from values measured without electrostimulation: P < 0.05.
