- argyrophil cells
Neuroendocrine cells that take up silver ions from a staining solution but require the addition of a reducing agent to precipitate metallic silver (unlike argentaffin cells which do not). Carcinoids of the foregut tend to be argyrophilic whereas those of the lower intestine tend to be argentaffinic.
