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

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 ...

New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

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 annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body ...

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 ...

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 ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...

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