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

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

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

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 ...

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 ...

Together with his student Hilde Mangold, the biologist Hans Spemann discovered the so-called »organiser« during embryonic development in 1924. In ...

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 ...

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 ...

Lipid and fatty acid metabolism is central to the maturation of the oocyte and the subsequent development of the embryo. Fatty acids serve not only as dense energy substrates but also as precursors ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

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 ...
