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 ...

What if you could precisely change the genome of a pre-implantation human embryo and then safely use that embryo to try to generate a healthier person? It’s a wild idea, but one that technology over ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

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 ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge techniques can accurately edit genes in human embryos—giving scientists ...

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 ...

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 formation of a human embryo is the point at which a human being begins to exist as a unique individual. There are complicating events, such as twinning, when an embryo splits into two — or ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...
