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

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

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 ...

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 ...

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 ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a group of specialized cells, known as "germ cells," which will later form ...
