It’s still one of the biggest mysteries in science: How does a human cell — too small to see with the naked eye — divide and reproduce to ultimately become a human body made up of more than 30 ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

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 ...

Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a ...

A new study examining mouse embryos when they are composed of just two cells, right after undergoing their very first ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

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 ...

Transforming human stem cells into embryo-like structures was previously unthinkable. Yet seemingly overnight, multiple teams published initial results that reach towards this goal. Each team has a ...

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 ...

Embryo freezing offers high success rates for couples delaying pregnancy. Learn who should consider it, how the process works ...
