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 ...

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, ...

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 ...

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

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 ...

So they turned their attention to the Iberian ribbed newt, which can regenerate not only body parts that are cut off but parts of its heart as well. There they focused on a molecule known as ...

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 ...

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 ...

By Priyanjana Pramanik, MSc. A large Chinese cohort study identifies early pregnancy as a sensitive window during which ...
