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 ...
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, ...
Together with his student Hilde Mangold, the biologist Hans Spemann discovered the so-called »organiser« during embryonic development in 1924. In ...
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 ...
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 ...
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 ...
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, ...
An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...
