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 ...

A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...

Scientists show that endocrine stem cells in the pancreas disappear after birth, and detail the genetic identity of the different types of pancreatic hormone-producing cells. The pancreas is a key ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

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 ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...
