1. Tissue distribution of MMP-9 and MMP-2 in adult rat brain.
Tissue distribution of MMP-9 and MMP-2 in adult rat brain. Sections of dorsal hippocampus demonstrating the distribution of MMP-9 and MMP-2 mRNA and protein are shown.A, Nissl staining of a hippocampal coronal section.mol. layer, Molecular layer; lacun. mol., lacunosum molecular layer; rad., radiatum layer. Scale bar, 1 mm. B, Tissue distribution of MMP-9 mRNA (in situ hybridization; left image) and protein (immunohistochemistry; right image). MMP-9 mRNA is enriched in neuronal fields of the hippocampus. The right image shows enrichment of MMP-9 protein in neuronal bodies of the dentate gyrus and the CA subfields. Diffuse MMP-9 protein staining, especially in the lacunosum molecular layer, can also be discerned.C, Tissue distribution of MMP-2 mRNA (left image) and protein (right image). In contrast to MMP-9, MMP-2 mRNA and protein are diffusely distributed over the entire hippocampus.
