The study found that removing germ cells affected the lifespan of male and female killifish differently. In females, germ ...

The cortical cords begin to break up into isolated cell clusters. The cords surround the primitive germ cells, forming ovarian follicles. The follicles replicate through mitosis, producing ...

The path of primordial germ cells illustrates the complexities of imprinted DNA, which contains epigenetic marks that turn on and off when necessary. Differences between the maternal and paternal ...

On the other hand, meiosis occurs with quite different kinetics in mammalian females. Female germ cells, or oogonia, stop dividing and enter meiosis within the fetal ovary. Those germ cells that ...

A germ cell tumor (mass) most often forms in the gonads. In females, they’re in the ovaries. In males, they’re in testes (TEST-eez). Ovaries are the 2 female glands where eggs form. They also make the ...

As in humans, female killifish live longer than males. However, when the researchers removed the germ cells from these fish, they found that males and females had similar lifespans. "After ...
