Gastrulation, the process where an embryo reorganizes itself from a hollow sphere into a multilayered structure, is considered a 'black box' of human development. This is because human embryos are ...

HeX-Embryoid model showing early blood cells (green) that have formed inside of blood vessels (red) surrounded by yolk sac mesoderm cells (blue) that support these tissues. University of Pittsburgh ...

Pioneering research led has provided new insight into formation of the human embryo. Pioneering research led by experts from the University of Exeter's Living Systems Institute has provided new ...

The signals orchestrating the transformation of cells into the highly organized structures of embryos have remained hidden from observation inside the womb. Now, scientists have illuminated early ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

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 developed a new laboratory model grown from stem cells that replicates the human amniotic sac in the first two to four weeks after fertilization. The structure, which the researchers ...

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that occur before birth and why many pregnancies fail. These models are made from ...
