Progressive Depletion of Rough Endoplasmic Reticulum in Epithelial Cells of the Small Intestine in Monosodium Glutamate Mice Model of Obesity

Figure 2

Representative light microscopy images showing histopathology of the small intestine. (a) Low magnification view of a hematoxylin-eosin- (HE-) stained section of small intestine from control mice. (b) Low magnification view of a HE-stained section of small intestine from monosodium glutamate- (MSG-) induced obese mice. Black boxes in (a) and (b) show the areas enlarged in (c) and (d), respectively. Arrowheads in (c) indicate intensely hematoxylin-stained regions in the cytoplasm. Double arrowheads in (d) indicate slight or negative hematoxylin-stained regions in the cytoplasm. Scale bars in (a) and (b) = 20 μm and (c) and (d) = 10 μm, respectively.
