Studying the shape of tissues and organs is critical to understanding how they are formed. Embryonic development happens in ...

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 ...

The limb is widely used as a model in developmental biology. Although the signalling pathways involved in limb development are largely conserved, striking morphological differences are observed among ...

Scientists reveal unprecedented insights into human limb development, including the many intricate processes that govern their formation. Human fingers and toes do not grow outward; instead, they form ...
