In 1978, Temtamy and McKusick classified isolated, non-syndromic Polydactyly and syndactyly, using a logical anatomical approach, into five distinct types for each group. Since then, there have been ...

Three-dimensional image of a developing limb bud generated using LimbLab. It shows where key genes are active during early limb formation. Sox9 (magenta) marks the cells that will become cartilage and ...

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 ...

A new study gives insight into how limb development evolved in vertebrates. The findings identify a gene that plays a central role in the evolution of limb development in vertebrates. By manipulating ...
