Cytological Features

The adenocarcinomas of the intestine induced in Syrian hamsters by N-methyl-N-nitrosourea (NMU) were of two histological types, superficial and intestinal. These types had distinctive characteristics regarding pattern, cytological features, secretion of mucus, and mode of growth. The histological changes induced by NMU in the mucosa of the small intestine differed from what has been described in enzootic intestinal adenocarcinoma and proliferative ileitis of Syrian hamsters. NMU produced alteration in the villous architecture and cytological change in the absorptive cells. There was marked shortening of the villi and reduced thickness of the mucosa. The villous absorptive cells were large and cuboidal with centrally placed nuclei.

Abstract Ferritin was identified in the absorptive cells of human jejunum from normal iron-replete subjects by the demonstration of the tetrad form of the iron hydroxide micelle of the ferritin molecule. In a few sections ferritin molecules were observed to be dispersed in the cytoplasm, but usually they were within inclusion bodies found in the apical cytoplasm. These ferritin-containing bodies were oval in profile and 0.5-1.5 µ long. They were not bounded by membrane but did have a moderately dense background substance which made a sharp boundary with the cytoplasmic ground substance. A few clues suggest that the body itself, but not necessarily its substance, is formed within the Golgi apparatus.

Macromolecular Architecture

The differentiation of the brush border which makes up the apical free surface of intestinal absorptive cells has been studied by electron microscopy. Specimens of Xenopus small intestine were fixed at various stages during metamorphosis, the time when a new intestinal epithelium forms. The interpretation of details described herein emphasizes the role of "surface-forming" vesicles. These vesicles are thought to provide membrane both for the initial expansion of the apical surface and for the later elongation of the microvilli. The latter are believed to be "molded" around filamentous cores that appear early in differentiation. The cores are attached to the apical membrane and extend vertically into the supranuclear cytoplasm. This interpretation rests chiefly on (a) the resemblance, both in morphology and in staining properties with colloidal thorium, between the membrane that limits the vesicles and that which limits the microvilli and (b) the distribution and time of appearance of the vesicles with respect to development of the microvilli. According to this view, the specific properties of surface membrane reside in preformed units that arise within the supranuclear cytoplasm. This morphogenetic process probably involves participation of the Golgi region as the site where the complex macromolecular architecture of the cell surface is assembled.
