Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organise and reorganise ...

Many pregnancies face challenges before a woman even knows she is expecting. One reason is the embryo’s rapid growth; any disruption during this stage can affect development. During week 3, the embryo ...

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 ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

Transposable elements, remnants of ancient viral DNA, are reactivated during the first hours and days following fertilization. This dynamic period of early development sees embryonic cells displaying ...

Scientists have captured the process of an embryo implanting in the uterus for the first time. Contrary to expectations, it has been revealed that the human embryo penetrates deeply into the uterine ...

The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered ...

Scientists find that close interactions between the mechanical properties of tissues and biochemical signalling between cells ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...
