Scientists in China this week say they’ve accomplished a first in bioengineering: creating embryo-like structures from monkey stem cells. The structures were implanted in surrogate female monkeys and ...

Scientists have been able to create stem cells that can mimic the early stages of mouse development. The researchers used only reprogrammed stem cells, not a fertilized egg, to create a synthetic ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study.

Researchers from the University of Cambridge have harnessed mouse stem cells to create model “synthetic” embryos that comprise a brain, a beating heart, and the foundations of all the other organs of ...
