Soc. Exper. Biol. & Med. 1927–8 25 439 The fibrillae are argyrophile, i.e., they are electively impregnated with silver. 1930 A. A. Maximow & W. Bloom Text-bk. Histol. iv. 95 Reticular or lattice fibers..are electively impregnated with silver by modified Bielschowsky methods after which they appear as black, sharply drawn nets... This gave them the name of argyrophil fibers. 1954 H. W. Deane in R. O. Greep Histol. xxi. 574 Included among the epithelial cells are numerous slender, bipolar cells containing neurofibrils and silverable granules (argyrophile cells). 1969 Anatomischer Anzeiger CXXV. 18 In type ‘c’ some of the granules in the cell are argyrophile as well as argentaffin. 1976 Path. Ann. XI. 201 The evolution of our concepts regarding the neoplasms arising from the family of endocrine (or neuroendocrine) cells, variously called Kultschitzky's, enterochromaffin, argentaffin, argyrophil, and basal cells, is a good example of the way ideas in pathology slowly germinate over decades. 1978 G. G. Brown Introd. Histotechnol. xv. 276 Argentaffin cell granules have the capability of reducing an ammoniacal silver nitrate solution to produce a visible black deposit of silver... This capability differentiates them from the argyrophil cells that cannot reduce ammoniacal silver solutions directly, but require the use of a reducing agent such as hydroquinone. 1985 Cancer 55 609/2 Argentaffin stain was negative, but argyrophil stain showed numerous positive neoplastic cells.

Greep Histol. v. 70 (caption) Kidney..stained by Pap's ammoniacal-silver nitrate method, illustrating the argyrophilia of reticular fibers in basement membranes. 1985 Jrnl. Clin.

V. Cowdry Textbk. Histol. xxv. 370 The second stage was the differentiation of delicate fibrils within the collagen..which began to exhibit an affinity for silver, in other words to become argyrophilic. 1959 W. Andrew Textbk. Compar. Histol. viii. 338 The capillaries of all vertebrates are lined by endothelium and present a thin wall having delicate fibers of argyrophilic, reticular type. 1978 Nature 26 Oct. 746/2 We found most argyrophilic debris rostral to the graft.
