A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

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

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, ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

You are the product of metamorphosis. During the third week of your embryonic existence, fateful genetic choices were made that began to transform a tiny ball of identical stem cells into a complex ...

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

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

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