The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Integrated screening and CRISPR reveal eleven previously unknown factors essential for early embryo development. They showed ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

A microscopic structure in mammalian egg cells called a meiotic spindle has one crucial job—and during egg maturation, it has only a few hours to do it properly. What happens in those few hours has ...

WASHINGTON (AP) — Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. SpaceX knocks out 3rd ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.
