p53 determines organ size

In studies conducted on the fruit fly, researchers at IRB Barcelona (Spain) headed by ICREA Professor Marco Milan have revealed that organs have the molecular mechanisms to control their proportions. In this process the protein ...

Embryos taking shape via buckling

The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.). According to a hypothesis ...

Discovery of 'mixer cells' could improve healing

French researchers from CNRS and Universite de Nice have recently identified cells that surprisingly change identity during embryogenesis in the Drosophila. By studying these "mixer cells" in a healing model, the scientists ...

Model may offer better understanding of embryonic development

A mathematical model developed at Purdue University can predict complex signaling patterns that could help scientists determine how stem cells in an embryo later become specific tissues, knowledge that could be used to understand ...

Mouse stem cells for primitive endoderm established

Stem cells that give rise to the mouse yolk sac have been isolated and cultured in the lab for the first time by RIKEN researchers, raising the possibility of artificially creating mouse embryos from stem cells in the future.
