Autoradiographic labelling using tritiated thymidine ([3H]TdR) was used to examine the pattern of development of gastric parietal cells in newborn pigs. Specific objectives were to establish sites in the gland where cells with a characteristic parietal cell morphology first appear, the extent of their migration or displacement, and the kinetics of any development and migration that occurs. Five newly-born littermate piglets were given a virtually continuous label of [3H]TdR over 24 hr, sacrificed at 1, 3, 5, 7 and 10 days thereafter, and samples of the gastric mucosa taken. The percentage of labelled parietal cells as a function of position in the oxyntic gland was measured for each pig. A g..View full abstract
