A dermatome is an area of skin that gets its sensation from a specific spinal nerve root. Spinal nerves exist in 31 pairs, one on each side of the spine. These nerves send signals for things like ...

In the most comprehensive analysis to date, researchers found that the shapes of fingerprints—whether they are circular, wavy, or winding—are influenced by the genes responsible for limb development ...

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing how a specialized signaling center shapes both cell identity and tissue ...

Human fingers and toes do not grow outward; instead, they form from within a larger foundational bud, as intervening cells recede to reveal the digits beneath. This is among many processes captured ...

Scientists have created a spatial atlas of the incredible process of human limb development, including steps that show digits emerging from a bud as cells recede, instead of growing outward. With ...

During early development, the embryo builds the body's organs by exchanging chemical signals between different cell types. When developing limbs, a thin band of skin cells at the limb’s surface, ...
