University of Sydney researchers have developed a new way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well, none yet fully ...

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 ...

Before most women know they're pregnant, an embryo has already begun organizing itself into the structures that will shape a developing body. Scientists have few opportunities to study those earliest ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Pioneering gene-editing treatments are already in clinical use, saving lives and easing the pain of devastating genetic diseases. However, the growing number of patients receiving these treatments ...

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 ...
