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 ...

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 ...

A confocal microscopy image of a nine-day-old human embryo, with specific proteins and cellular structures colored distinctively. Green relates to embryonic stem cells and magenta associates with ...

For the first time in history, scientists have captured on film the moment a human embryo implants itself—an elusive biological milestone that has long been considered a “black box” in early human ...

Scientists have captured a video showing the implantation of a human embryo for the first time, using a laboratory model of a uterus. When you purchase through links on our site, we may earn an ...

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 ...

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 - ...
