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 ...

Human development is a beautiful, complex process. Beginning from just two germ cells, the cells divide and double until an entire organism is developed in just under a year. While studying embryos in ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab experiments, vanillin caused embryonic stem cells to lose their ability to ...

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 - ...

In the normal embryo (left): magenta cells will become the placenta, yellow cells will become the yolk sac, and cyan cells will become the epiblast, which later forms the body. In the embryo where ...
