The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

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 ...

Technological, ethical and legal issues have limited the understanding of the early stages of embryonic development in humans, despite its importance in basic developmental biology and reproductive ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

LONDON (Reuters) - Scientists in Britain have applied for a license to create hybrid embryos using human cells and animal eggs for stem cell research to develop new treatments for diseases such as ...

Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals. One of the longest-standing questions in biology ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...
