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 ...

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 ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

An international study led by the medical Faculty of the University of Bonn has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations ...

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 ...

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 ...

Technological, ethical and legal issues have limited the understanding of the early stages of embryonic development in humans, despite its importance in basic developmental biology and reproductive ...

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