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 ...

With weMERFISH, the MERFISHEYES atlas and the integration of live imaging, researchers now have a new tool at their disposal.

Researchers have discovered and characterized a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the ...

“A central question has been: How do thousands of genes work together in an embryo, and how is their activity linked to the movement of cells?” says first author Yinan Wan. To answer this question, ...

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 ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late developmental stages but resemble one another more during mid-embryogenesis, a ...
