Milinkovitch and his co-author Rory Cooper, now a research fellow at the University of Sheffield in the U.K., showed how a particular gene, the whimsically named "Sonic Hedgehog" gene, is important in ...

Chickens treated to inhibit the sonic hedgehog (Shh) pathway during development grow feathers that resemble ancient ...

Here, feather buds are seen on the 12th day of incubation. A gene named 'Sonic Hedgehog' plays a crucial role in embryonic development. By disrupting this gene, scientists were able to temporarily ...

Explore the fascinating world of dinosaur feathers and their evolution through groundbreaking research on chicken embryos.

They succeeded, but only temporarily. By inhibiting the key gene Sonic Hedgehog at the stage of embryonic development, scientists have managed to make chicken feathers more similar to the tubular ...

Alteration of the expression of the co-called 'Sonic Hedgehog' gene can transform feet scale and wing feathers. While a transient over-expression of the gene can permanently turn feet scales into ...

From two weeks onwards, feather development in the embryos partially returned to normal. The chicks with the altered pathway ...

The Sonic Hedgehog gene requires these enhancers for limbs to fully develop. “In lizards, Sonic Hedgehog stays on and acts as the motor, driving limb development down into the fingers and the ...

Tweaking the Sonic Hedgehog gene can transform different aspects of development in chickens. For instance, transient over-expression of the gene can permanently turn feet scales into feathers. But ...
