Investigating the Effects of an MMP-inhibitory Biomaterial on the Host Inflammatory Response using an Air Pouch Mouse Model

Patel, Ritesh 13 January 2011 (has links)
An earlier approach to restore homeostatic levels of ECM degrading matrix metalloproteases (MMPs) by the Sefton Lab utilized hydroxamate-based MMP inhibitory (MI) beads. While the MI beads delayed ECM degradation in the context of skin wound healing, they caused elevated cell infiltration in a subcutaneous implant model. The primary goal of this project was to further investigate this finding using an air pouch implant model in mice and a different control group – methacrylic acid-based (MAA) beads. Exudate analysis indicated that the MI beads, implanted subcutaneously with gelatin discs, elicited a similar biological response as the MAA beads. Exudates corresponding to both biomaterials had similar cell counts and chemokine levels, which were greater than those corresponding to the control used earlier, poly-methyl methacrylate-based (PMMA) beads. Further, both MI and MAA beads activated infiltrating macrophages in the classical manner, and influenced the activity of an MMP8 catalytic domain in a similar manner.
