The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

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 ...

Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined ...

Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to ...

At the moment of fertilisation, the genes in the fertilising sperm and egg are switched off. For a new embryo to develop, they must be switched on – but how? The answer is unknown, which seems ...

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 ...

The model demonstrates never-before-seen potential in human pluripotent stem cells Key takeawaysFor the first time, stem cells typically considered ...

The embryonic receptor "Smoothened" regulates dopamine and acetylcholine timing to control learning and habit formation in adults.
