Figure 2. MPO activity in supernatants of muscle cells or muscle cells with neutrophil co-cultures.

Conditions were identical to those used in Fig. 1A except that all treatments used 25 000 neutrophils mm⁻². * Significantly different from corresponding non-loaded treatment. # Significantly different from muscle cells without neutrophils treated under otherwise identical conditions. P < 0.05. n = 6 per treatment. Bars represent s.e.m.
