A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

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.

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 ...

Zoe Strozewski is a Newsweek reporter based in New Jersey. Her focus is reporting on U.S. and global politics. Zoe joined Newsweek in 2021. She is a graduate of Kean University. You can get in touch ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its ...

What happens in the first weeks after a human embryo implants in the uterus has been a black box. Now, biologists have had a chance to study this stage of development in detail for the first time. The ...

Researchers from the University of Adelaide have discovered that the earliest days of embryo development have a measurable ...
