[Argentaffin cells in human adenohypophysis].

Appropriate techniques such as Bodian's method demonstrate numerous argyrophilic cells in the adenohypophysis of man. These cells were shown by subsequent staining methods to be chromophobe cells. Furthermore, beta cells may also be impregnated by the method of Bodian, but display a much less intense argyrophilia than the first mentioned cell type. Both cellular forms react positively to diazotation techniques used to demonstrate indol radicals. This findings should be related, for instance, with the demonstration of indolamines in beta cells by the technique of induced fluorescence.
