Failure of chromosomal organization within human egg and sperm cells result in miscarriages and infertility. However, the mechanisms controlling these processes are not understood. The discovery of a ...

To understand why egg cells are more susceptible to errors, Wignall studies a football-shaped structure, called the spindle, which organizes genetic material before the egg divides. "The spindle is ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

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 Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build and coordinate the internal scaffolding needed to create a healthy egg. The ...

In our cells, our DNA carries chemical or 'epigenetic' marks that decide how genes will be used in different tissues. Yet in the group of specialised ...

Scientists at Oregon Health & Science University (OHSU) have successfully transformed human skin cells into egg cells, marking a significant advancement in fertility research. This breakthrough offers ...

A snapshot from a simulation of how microtubules bend and direct material in a maturing egg cell into a twister-like flow. Egg cells are the largest single cells on the planet. Their size — often ...
