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 ...

Hierarchical communication between cells with distinct positional memories orchestrates the regeneration of missing limb structures in axolotls.

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 ...

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 ...
