Uranaffin reaction of Merkel corpuscles in the lingual mucosa of the finch Lonchula striata var. domestica.

摘要

Subepithelial Merkel cells in the tongue of the finch were investigated by use of the uranaffin reaction. The results indicate that the secretory granules of subepithelial Merkel cells in this animal are positive for the uranaffin reaction, and in this respect are cytochemically similar to those reported in mammalian intraepithelial Merkel cells.
