Organellae were abundant from the perinuclear region to the intermediate region of the ooplasm. Especially smooth surfaced endoplasmic reticulum (sER) of small vesicular type containing intracisternal granules were abundantly observed. The cisternae containing granules constitute the network branching and anastomosing in all directions throughout the ooplasm. With the morphological transformation of sER, the cisternae become to fill with granules, and granules aggregate to form granular masses, increasing in its number and electron density. During the growth of the oocyte, they may undergo physiochemical changes resulting in a homogeneous yolk body., 長崎大学教育学部自然科学研究報告. vol.23, p.87-100; 1972}, pages = {87--100}, title = {オカダンゴムシにおける卵黄形成の電子顕微鏡的観察}, volume = {23}, year = {1972} }
