All vertebrate embryos follow a common developmental path due to their common ancestry. All have a set of very similar genes (the homeobox genes) that define their basic body plan. As they grow, the ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

Researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form. Can a single ...

We often think of embryonic development as a genetic ballet, choreographed entirely by DNA and proteins. But there’s another cast member quietly shaping the scene: lipids. These fat molecules aren’t ...

Researchers have developed a theoretical framework that can reproduce and predict the patterns associated with gastrulation in a chicken embryo. Gastrulation is one of the most important phases in ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

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 ...

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 — ...
