In addition to endodermal and mesodermal cells, alcohol causes changes in DNA methylation in ectodermal cells (in blue), from which the nervous system and brain develop. During the tightly regulated ...

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. In ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy. It's one of life's most defining moments -- that crucial ...

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 ...

A team of researchers said Wednesday that it had produced embryonic stem cells -- a possible source of disease-fighting spare parts -- from a cloned human embryo. Scientists at the Oregon Health and ...

Egg whites may be perfect for a health-conscious breakfast, but egg yolks turned out to be the key ingredient for cultivating ...

The embryos weren’t used to try to establish a pregnancy, but the researchers behind the technique say it could one day be ...
