Gland
Definition:

Vitellogene
Definition:
(n.) A gland secreting the yolk of the eggs in trematodes, turbellarians, and some other helminths.
Example Sentences:
(1) Significant changes in cytosolic and nuclear hepatic estrogen receptor levels correlate with vitellogenic stage.

(3) The cephalic signal can be superseded by juvenile hormone, whose presence is necessary for each follicle to become vitellogenic.
(4) The numbers of vitellogenic oocytes in the ovary during the entire study also suggested that atresia of vitellogenic oocytes does not play a prominent role in determining fecundity.
