Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Healthy development The researchers found that higher variability in cell division leads to a more optimal arrangement of cells within the embryo, which promotes healthy development. "Our work ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

The American Society for Reproductive Medicine published a report that concludes preimplantation genetic testing for ...

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 ...
