In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted ...

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 ...

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 ...

(CNN) — 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 ...

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 - ...

Researchers said their model mimics certain key features of a 20-day-old human embryo but does not have the potential to develop into one. Sign up for the top news stories every day to keep you ...

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 ...

Proposal for embedded ethics, based on dynamic dialogue, to facilitate ethically responsible research with stem-cell-based embryo models.
