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 ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

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

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

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

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

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...
