FIGURE 7. Active MMP-13, but not its zymogen, activates pro-MMP-9.

FIGURE 7

A, purified active MMP-13 and pro-MMP-13, at the indicated dosages, were incubated with purified pro-MMP-9 for 16 h followed by zymography. B, active MMP-13 was incubated with pro-MMP-9 in the presence or absence of the MMP inhibitor or chymostatin for 16 h followed by zymography.
