Fine Structure of the Granulosa Lutein Cells of Pregnancy in Carnivora
The ultrastructure of granulosa lutein cells of pregnancy from 10 raccoons ( Procyon lotor ), 8 crabeater seals ( Lobodon carcinophagus ), 3 black bears (Ursus americanus), a palm civet ( Paradoxurus hermaphroditus ) and a dog ( Canis familiaris ) was studied. Fetuses ranged from 10-130 mm crown rum...
