The ultrastructure of cortical granules and cortical alveoli in the eggs of Japanese palolo (a polychaete, Tylorrhynchus heterochaetus) was studied electronmicroscopically, utilizing various cytochemical stainings.
The dense components of the cortical granules were stained with alcoholic phosphotungstic acid (PTA) (block staining), aqueous PTA, periodic acid (PA) -silver and PA-PTA. The filamentous substance in the cortical alveoli (stored jelly substance) was also stained with aqueous PTA and PA-PTA, but not with PTA (block staining) or PA-silver. The components of both granules are discussed cytochemically.
