Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

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, ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

A "synthetic" embryo with a brain and beating heart has been created by British scientists. It features the foundations of all the body's organs, including neural and gut tubes that protect the ...
