Dalhousie University provides funding as a member of The Conversation CA-FR. In January 2017, I met Jiankui He, the now-infamous Chinese scientist who would go on to create the world’s first ...

Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post ...

The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...

A team of scientists has created synthetic human embryos from stem cells, without the need for either an egg or sperm — a remarkable breakthrough that raises plenty of thorny ethical questions. While ...

Gleaning stem cells from cloned monkey embryos, as a team of Oregon researchers has done, is an impressive step. But it probably won't lead to medical treatments anytime soon. One hurdle is ethical ...

Scientists have cultivated monkey embryos in the laboratory long enough to watch the beginning of organ formation and the development of the nervous system — milestones that are difficult to observe ...

Two research groups have independently produced human embryonic stem-cell lines from embryos cloned from adult cells. Their success could reinvigorate efforts to use such cells to make ...

Assistant Professor of Obstetrics and Gynecology, School of Medicine, University of Washington Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life ...

A researcher holding human embryonic stem cell cultures in 2004. In the new research, scientists use human stem cells to make models similar to human embryos. The models cannot develop into fetuses.
