Eight years on from the formation of the Human Cell Atlas (HCA) consortium, which set out with the hugely ambitious task of mapping the entire human body – around 37.2 trillion cells – scientists ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to ...

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 ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...
