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 ...

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 ...

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, ...

Maternal exposure to sulfur dioxide during the first trimester was associated with higher odds of congenital limb defects in ...

Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated. An international collaboration that includes ...

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 ...

Fingerprints are among the most distinctive features of human biology, serving as enduring identifiers for individuals and as windows into genetic and developmental processes. The three major ...

Perhaps like a limb with multiple digits? The team will also try reintroducing the genes in tetrapod species, which normally lack the genes, to see how they affect limb development. "We will continue ...

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 ...
