Rat cannulation injury site.
Comments welcome re the fact that MMP9 appears to be positive in a subset of CD68 positive macrophages.
Antibody should be further diluted ( 1/3K used). Positivity appears confined to macrophages of the red pulp sinusoids.
Germinal centres show positive dendritic macrophages ( black arrowhead)
Rounded, smaller macrophages are seen in the high endothelial venules ( red arrowhead)
In the muscularis externa positivity is seen only in the nuclei of
?satellite cells? associated with the ganglion cell bodies of
Auerbach’ s plexus

I am not familiar with this protein: comments welcome.
