Figure 3: Effects of SEI on ECM degradation by leukocytes in response to LPS + FMLP. Leukocytes from the species identified were stimulated by LPS + FMLP either in the absence (black 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.
