In mammals, signalling between the placenta and the embryo is essential for successful development. Here, a quantitative, time-resolved model describes the coordinated formation of the mouse embryo ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab experiments, vanillin caused embryonic stem cells to lose their ability to ...
