Abstract
|
|
|
To investigate the structural and scanning electron microscopic characteristics of the aggregations of enteroendocrine cells in the duodenal mucosae from 2 human fetuses of 22 weeks of gestation, paraffin and frozen section slides were
employed,
Slides were stained with
hematoxylin and eosin, Azan, Gomori and scanning electron microscope was used to study the fine structures of the cell surfaces.
@ES The results obtained were as follows;
@EN The aggregations of enteroendocrine cells were observed in the fetuses of 2 weeks of gestation. The shapes of the cell aggregations were concaved toward gut lumen and convexd toward basal lamina. The cells of aggregation formed strata
and
Goblet cells were observed near the get luminal surface. Only a few cell aggregations were found in the duodenal villi and characteristic dent on the top of the villus shows the concave surface of the aggregation of enteroendocrine cells
by
scanning electron microscopic observation. The luminal surface of the cell aggregations was devoid of microvilli and variable sizes excretory membrane-bounded granules were observed.
