In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...

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 ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

A single-celled creature originally found in shallow sea sediments around Hawaii develops into multicellular structures with remarkable similarities to animal embryos. The finding could help ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

Embryo development in livestock underpins global food security and genetic improvement programmes. From the first mitotic divisions in the zygote to the formation of the blastocyst, the timing, ...

Most animals, including humans, have bilateral symmetry, which means our bodies are pretty symmetrical. At least on the outside. On the inside, things are different. "If you look at our insides, we ...

Superovulation and embryo transfer form a cornerstone of modern cattle breeding, enabling rapid dissemination of superior genetics by inducing multiple ovulations in donor cows and transferring ...

In a bid to improve organ transplant options in the future, a team led by researchers at the Chinese Academy of Sciences has shown that it's possible to produce pig embryos containing "humanized" ...

LONDON (Reuters) - Scientists in Britain have applied for a license to create hybrid embryos using human cells and animal eggs for stem cell research to develop new treatments for diseases such as ...

CRCHUM researcher Sophie Petropoulos and her team reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of ...
