Germ cell development and oogenesis represent central processes in the reproduction of invertebrates, exhibiting remarkable diversity in cellular architecture, developmental mechanisms and functional ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Mammalian oocytes utilize a conserved combination of cell cycle control, cytoskeletal organization, and polarity pathways that are fundamentally shared with other vertebrates and invertebrates.

Infertility affects approximately 1 in 6 people in their lifetime worldwide according to the World Health Organization (WHO). Infertility —as defined by the American Society for Reproductive Medicine ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
