A team of researchers in the United States and the United Kingdom says they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm ...

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

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

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

Morphogens are the secreted molecules that pattern embryonic tissues. These molecules are important not only for the embryo during development, but also for the adult during tissue repair. However, ...

Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post ...
