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, ...

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 ...

A new model for embryo research Unlike other common laboratory animals, such as mice, guinea pigs have a preimplantation development that is more comparable to that of humans in terms of timing and ...

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 ...

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

LaBonne is president of the Society for Developmental Biology and the Erastus Otis Haven professor of molecular biosciences at Northwestern University. Imagine a world without lifesaving medicines, ...

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 ...

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 ...

Megan covers the intersection of science and society. How is biomedical research funded? Who benefits? And how do new technologies reflect and shape our values? You can reach Megan on Signal at ...

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 ...
