Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is surprisingly conserved across jawed vertebrates. The real differences ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

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 ...

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, ...
