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 ...

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 ...

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

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 ...

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 ...

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

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 ...
