Figure 4: Effects of SEI on ECM degradation by leukocytes in response to HKS. Leukocytes from the species identified were stimulated by HKS either in the absence (grey bars) or presence (hatched bars) of 10 μM CE-2072. Matrix degradation is expressed as the percentage of radioactivity recovered in the supernatant relative to the total amount of radioactivity present in the matrix preparation. Each value is the mean ± SEM of 6 or more measurements.
