Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Technological, ethical and legal issues have limited the understanding of the early stages of embryonic development in humans, despite its importance in basic developmental biology and reproductive ...

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 ...

Researchers announce the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, out of mouse embryonic stem cells. Just two weeks after ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells.

A proposed international legal and ethical definition could address current challenges, with implications for improving IVF success rates. The ethical and legal challenges posed by embryology research ...
