[Further contribution on the fine structure of fetal goblet cells. Investigations on the small intestine of cattle].
Early in the fetal development, i.e. at the time both of the growth of intestinal villi and crypts and the epithelial cell differentiation the goblet cells also appear. The maturation of goblet cells progresses during their migration from the base of the villi respectively of the crypts to the villous top. As in the bovine large intestine there are vesicles and capsulated vacuoles, which contain vesicles, as single elements or as conglomerates in the immature goblet cells of the small intestine. These images deliver a scenario of the mechanism of secretory granule production and probably play a role in the formation of mucus.
