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

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

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 ...

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 ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

Scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development. Their optical system could guide the design of synthetic, light-activated cells for ...

Infertility is a major healthcare concern. Understanding the molecular regulators governing fertilization, early embryonic ...
