Example text

The fact that GHIDINI was unable to show any asynchrony in the appearance of the two cell types may be due to some malfunction of the argentophil technique employed; in fact, he mentions an equal number of argentaffin and argentophil cells. Besides, the present writer has come across conditions of this sort, due to defective silver impregnation, which, in any case is rather erratic. e. the development), the same number of cells can show a positive reaction. Obviously, this leads one to think that the appearance of the argentophil pre-enterochromaffin cells occurs earlier than the 241 st hour.

In the latter there seem to be phenomena of "luminescence" in the dark field, and histochemical characteristics which might point them out to be responsible for the secretion of glucagon. At this point, we should also consider t,he non-argentophil pre-enterochromaffin clear cells and the empty cells, but as already explained, the information available is too scarce. 3. Embryology of the enterochromaffin cell The data on embryonic development may be grouped under three different chapters: a) time of appearance and characteristics of the first identifiable cells, b) experimental embryology, c) discussion on the origin of the enterochromaffin cells.

And CERIOTTI 1939a) and the oviduct of the lizard (VIALLI and CERIOTTI 1939), seem to extend the range of possible derivations to mesodermic epithelia. The recent data of FIORE~TI~I and MIRA (1963) on the presence of enterochromaffin cells in the buccal epithelium and in the aditus ad laryngem of Amphibians even raise the question of a possible origin from ectodermic epithelia. The sum total of these partially contrasting data indicates that the que;,;tion of embryological origin requires further study, possibly with emphasis on the experimental approach.
