Figure 3A shows the survival of WT mice following intraperitoneal implantation of either a WT or MMP8 null cecum. WT mice that received a MMP8 null cecum (MMP8 null into WT, n=7) had a significant survival advantage over WT mice that received a WT cecum (WT into WT, n=9, *p<0.05). Figure 3B shows survival of MMP8 null mice following implantation of a WT or MMP8 null cecum. Mice that received a MMP8 null cecum (MMP8 null into MMP8 null, n=8) had a significant survival advantage compared to those that received a WT cecum (WT into MMP8 null, n=8, ***p<0.001).
