Aggregation of macrophages in the tips of intestinal villi in guinea pigs: their possible role in the phagocytosis of effete epithelial cells.

abstract：:Membrane-coating granules of the epithelium of the hamster cheek pouch displayed a lamellated internal structure consisting of alternating thick and thin electron dense bands separated by translucent bands of equal width. The repeat distance of the contents was 8.5 nm +/- sd. 0.7 nm and the thickness of the major elec...
