For MMP9 (m/z = 959.404) spatial distribution in bovine (Figures 7G–I) and porcine (Figures 7J–L) granulomas, epithelioid macrophages, multinucleated giant cells, and neutrophils and fibroblasts from the periphery of granulomas were immunolabeled in both species (Figures 7I, L). This evidence concerns the gene MMP9 and Granuloma.
