#DBfeature 🦈🦷 Evolution, development, and regeneration of tooth-like epithelial appendages in sharks by Ella Nicklin, Gareth Fraser et al Ella Nicklin Gareth Fraser sciencedirect.com/science/articl…

🚨🐣 Our new paper is out PLOS Biology! Sonic hedgehog inhibition transforms feathers into ancestral protofeathers-like structures. These units recover after hatching, highlighting their remarkable developmental robustness! journals.plos.org/plosbiology/ar… The Milinkovitch-Tzika lab

🦖➡️🕊️ From dinosaur simple proto-feathers to bird intricate feathers? Our latest study shows that feather development is highly resilient to perturbations. 🧐✨ Read more here 👉 lanevol.org/news/article/d… #evolution #feathers #dinosaurs #birds Université de Genève Biologie - UNIGE

Check out these feather buds on the chicken embryo's wing! Our latest PLOS Biology reveals that temporary inhibition of sonic hedgehog signalling transforms feathers into simple, protofeather-like structures—similar to those of their dinosaur ancestors🔬🦖 journals.plos.org/plosbiology/ar…

On the train to #biologists100! Come check out poster 185 and talk to me about organs that grow from the skin 🐣 🐊

Come check out poster 185 in tonight's session at #biologists100 🐣! And for more detail, here's the full article recently published in PLOS Biology 🔬 journals.plos.org/plosbiology/ar…

Animal appendages, such as feathers, hair, and scales, usually develop as genetically controlled units during embryo development. There are some exceptions to this rule, such as the head scales on crocodiles, which have been found to be produced by purely mechanical processes.

New Pre-Print Alert! "Teeth Outside the Jaw: Evolution and Development of the Toothed Head Clasper in Chimaeras." We use fossil evidence, development and CT scans through ghost shark ontogeny to describe the emergence of the unique tenaculum! 👻🦈🦷 biorxiv.org/content/10.110…

Thrilled that our image was selected for the cover of Royal Society Publishing's Open Biology! We experimentally induced a developmental shift from normal footpad scales to mechanically-driven folding on chicken embryo digits 🐣🔬. Stay tuned—the full article is coming soon! 🧪 #DevBio

Great to see our chicken wing image featured on the cover of PLOS Biology 🐣🔬! To learn more about how these feathers develop, check out the full article here ⬇️ journals.plos.org/plosbiology/ar… The Milinkovitch-Tzika lab Genetics & Evolution

Check out our new research in Royal Society Publishing's Open Biology! We experimentally induce a transition from chemical to mechanical patterning on the footpad of the chicken embryo 🐣🔬 The Milinkovitch-Tzika lab royalsocietypublishing.org/doi/10.1098/rs…

This is the leg of a hatchling chicken, showing their precisely arranged scales 🐣. Read our new article in Royal Society Publishing's Open Biology to learn how they develop, and how we can mechanically transform them into a pattern of brain-like folds! royalsocietypublishing.org/doi/10.1098/rs…

🚨 We make the cover of Open Biology! Boosting sonic hedgehog signalling in chicken embryos flips the script of skin patterning—chemical pre-patterns give way to mechanical folding. 🧬 From Turing to tissue mechanics. 🧪 ➡️ royalsocietypublishing.org/doi/10.1098/rs… Université de Genève Royal Society Publishing

ICYMI, our new work in Royal Society Publishing's Open Biology shows how mechanical forces can drive patterning. By altering growth & material properties of the chicken embryo's skin in vivo, we induce a shift from molecular to mechanical patterning 🐣 🔬 royalsocietypublishing.org/doi/10.1098/rs…

Excited to share our new research in iScience journal ! We reveal that tortoise head scales are sculpted through two distinct developmental processes - chemical signalling and mechanical folding 🐢🔬 The Milinkovitch-Tzika lab Genetics & Evolution cell.com/iscience/fullt…

Squishing jellies!! thenode.biologists.com/squishing-jell… via the Node thank you for the opportunity to share this behind the story of my postdoc article from the Roux Lab

This is the skull of a tortoise embryo imaged with light sheet microscopy. Check out our new article in iScience journal to learn how both chemical signalling and mechanical forces sculpt their intricate head scales 🐢🔬 cell.com/iscience/fullt…

A UNIGE study reveals that turtles use both genetic signals and mechanical forces to develop the scales on their heads, highlighting a shared evolutionary heritage with crocodiles and dinosaurs. The Milinkovitch-Tzika lab #UNIGE #research #science ow.ly/yLVK50W6O2Q

Head scales of the Sulcata tortoise, imaged with light sheet microscopy. Our new study in iScience journal reveals that their emergence is controlled by both chemical cues and mechanical forces. Read the full article here 🐢🔬 cell.com/iscience/fullt…
