Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

In mammals, signalling between the placenta and the embryo is essential for successful development. Here, a quantitative, time-resolved model describes the coordinated formation of the mouse embryo ...

Researchers at Kenya’s Ol Pejeta Conservancy witnessed a biological breakthrough recently when a southern white rhinoceros ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

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, a group now ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

Australian scientists have discovered quail eggs can help them understand birth abnormalities and other developmental health concerns. They use these eggs to observe embryos in real-time and in high ...

For nearly three days after a sperm meets an egg, the human embryo (a tiny, eight-cell blob) is managed by the egg’s genes. On day three, the embryo strips its entire genome naked, freeing itself of ...
