China has delivered the world's first human artificial embryo models to orbit to test how microgravity affects human ...

Embryo organoids made from stem cells are enabling scientists to recreate early pregnancy in the lab, unlocking treatments ...

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 ...

China has become the first nation to send human artificial embryos into orbit, aiming to uncover how space conditions like ...

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 ...

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 ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

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 ...

The stem cell-based embryo model and actual human embryos share many characteristics but are distinctly different. However, internationally, not everyone agrees on the definitions and what we should ...
