Abstract

The microvillous border of normal, developing and degenerating planarian retinal clubs was examined using osmium and glutaraldehyde fixation. Well-developed normal photoreceptors contained well preserved microvilli both after osmium and glutaraldehyde fixation. Osmium-fixed regenerating and degenerating retinal clubs showed serried vesicles and anastomosing tubules at the site of the microvillous border. After glutaraldehyde fixation, chains of vesicles were absent and the photoreceptor consisted of a regular array of microvilli. This difference indicates the selective sensitivity of the photoreceptor membranes in regenerating and degenerating retinal clubs to the action of osmium tetroxyde.
