Yeah but check out these pharyngeal arch neural crest cells

I’m in the same boat. Autoreply says 1/30. Hopefully NIH pushes back this requirement until they can fix this bug.

Wonderful collaboration of Claire Arata and co-first-author Elena Vasileva from Amatruda lab. Claire provided the neural crest driver and Elena the EWS oncofusion. Best combination since PB&J. Amazing that expression of a single oncofusion in crest produces ectopic fins.

Wonderful to have my second ever grad student stop by the lab today. Elizabeth Zuniga. She is now faculty working on eye development at Baylor College of Medicine. Such joy to see your former trainees doing so well.

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team!

Teeth first evolved as sensory tissue in the armored exoskeletons of ancient fish, fossil scans find
Anyone who has ever squirmed through a dental cleaning can tell you how sensitive teeth can be. This sensitivity gives important feedback about temperature, pressure—and yes, pain—as we bite and chew ...

When did the lubricated joints that allow our skeleton to swivel, rotate and bend evolve? @crumplab.bsky.social explores a new @plosbiology.org paper by @neelimasharma.bsky.social &co that pinpoints their origin to the earliest jawed vertebrates 🧪 Paper: plos.io/3CTC8La Primer: plos.io/4kkhXa6
Left: A phylogeny of chordates, flanked by images of a lamprey, a placoderm, a brown shark, a longnose gar and a hawksbill turtle. Agnathans such as lampreys lack synovial joints. The first putative evidence of synovial joints in the fossil record is in early gnathostomes such as the antiarch placoderm fish that lived during the Silurian and Devonian periods. Modern gnathostomes such as cartilaginous fishes (i.e., chondrichthyans such as the brown shark), bony fishes (i.e., osteichthyans such as the longnose gar), and limbed vertebrates (i.e., tetrapods such as the Hawksbill turtle) possess synovial joints in their jaws, fins/limbs, and other locations. All images used are freely available without copyright restrictions. Top right: a typical agnathan joint is shown where glycosaminoglycans and proteoglycans are uniformly distributed across the cartilages (blue) that are connected by fibrous tissue (olive). Bottom right: a typical gnathostome synovial joint is shown where surface cartilage has a unique proteoglycan composition from the underlying cartilage and bone, and a fluid-filled cavity separates adjacent skeletal elements.
