Bovine embryos as a model for early human development

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, LMU researchers argue that bovine embryos might well be a better model for early human development than the mouse ...

A dictionary of the language of cells

In their struggle to survive and prosper, multicellular organisms rely on a complex network of communication between cells, which in humans are believed to number about 40 trillion. Now, in a study published in Nature Communications, ...

X-ray tomography on a living frog embryo

Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related ...

X chromosome inactivation

Each cell in a woman's body contains two X chromosomes. One of these chromosomes is switched off, because nobody can live with two active X chromosomes. Hendrik Marks and Henk Stunnenberg, molecular biologists at Radboud ...

Stem cells organize themselves into pseudo-embryos
