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 ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. A new study using stem ...

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 ...

A pair of research teams unveiled two new ways to replicate a key structure from the earliest days of embryonic development — an advance that could provide important new insight into human development ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside ...

The first stages of placental development take place days before the embryo starts to form in human pregnancies. This new finding highlights the importance of healthy placental development in ...

A team of researchers in the United States and the United Kingdom says they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...
