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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 ...

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 ...

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 ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

In a longitudinal study published in Scientific Reports, researchers investigate the effect of maternal physical activity on the size and growth of the yolk sac during early pregnancy. To this end, ...
