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 ...

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 ...

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 ...

To shed light on the principles that govern tissue dynamics across species, RIKEN biologists have developed a new method for analyzing the development of vertebrate limbs. These principles could help ...

This study is reported by Jia-Tang Li’s group from the Chengdu Institute of Biology, Chinese Academy of Sciences. The development of limbs is significant for the origin and evolution of tetrapods, ...

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, ...

New information about molecular mechanisms of development can be combined with existing knowledge about embryology, anatomy and paleontology to allow for an increased understanding of evolutionary ...

Snakes used to wander the Earth on legs about 150 million years ago, before they shifted from strut to slither. Now, two scientists have pinpointed the genetic process that caused snakes to lose their ...
