In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires precise coordination; otherwise, the embryo could develop serious complications ...

A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body, a remarkable structure that organizes essential molecules to guide early ...

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 ...

Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...
