The oviduct plays an indispensable role in mammalian reproduction by not only transporting gametes and embryos but also by providing a finely tuned microenvironment that supports fertilisation and ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, scientists identified a single-celled marine organism called Chromosphaera ...

Consider the crustacean Parhyale hawaiensis, a tiny crustacean with some interesting attributes. “It’s been called a ‘living Swiss army knife,’” said Dillon Cislo, the lead author of a study that ...

The role of Fibroblast Growth Factor 8 (FGF8) in embryonic development and organ formation is gaining increased recognition as scientists uncover its wide-ranging influence. FGF8, a powerful signaling ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

The crustacean Parhyale hawaiensis (P. hawaiensis) organizes its cells in a grid-like pattern during embryo development, relying on grid patterning rather than chemical signals to dictate cell ...

Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, researchers have shown for the first time what exactly happens in the ...
