Researchers announce the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, out of mouse embryonic stem cells. Just two weeks after ...

Morphogens are the secreted molecules that pattern embryonic tissues. These molecules are important not only for the embryo during development, but also for the adult during tissue repair. However, ...

External views of mouse embryos after 10.5 days of embryonic development. The embryos on the left show a technique for revealing where individual genes are expressed (Wnt1, Wnt5a and Wnt11). The ...

Do synthetic mice dream of electric sheep? We’re on the way to finding out thanks to a breakthrough in stem cell research. It’s not going to overthrow mankind from a lab anytime soon, but a stell cell ...

Researchers from the University of Cambridge and Caltech have created model mouse embryos from stem cells—the body's master cells, which can develop into almost any cell type in the body—that have ...
