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

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

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Described in a paper in the journal Cell, the model allows scientists to study interactions between the womb and embryo, and ...

Researchers have mapped the complex molecular interactions that occur during the earliest stages of human development. New international research shines a light on the role of transcription factors ...

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

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...
