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 ...

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 ...

Some animals in the world possess the ability to regenerate tissues, allowing them to regrow parts of limbs or entire limbs after amputation. In a study published in the journal PNAS, a ...

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, ...

Globally, close to 60 million people are living with limb loss. Amputations can result from various medical conditions such as tumors, infections, and birth defects, or due to trauma from industrial ...

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 ...
