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

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

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

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

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 ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a ...

A team at the University of Cambridge has announced making the first human “synthetic embryos” – embryo-like structures made from stem cells – that have been grown to a stage equivalent to just past ...

The model allows scientists to study interactions between the womb and embryo, and look for causes behind implantation ...
