There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station.

Week 3 of pregnancy is a delicate stage when the embryo undergoes rapid cell division and early organisation. At this point, ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
