Check out this great opportunity! 🐸

1 little, 2 little, 4 little blastomeres… Xenopus tropicalis cleaving embryo timelapse By Helen Willsey (during postdoc with Richard Harland using a ZEISS Microscopy scope from Patel Lab)

Happy fluorescence Friday from these explanted Xenopus mesenchymal cells stained for microtubules (grey), actin (blue) and nuclei (magenta) 🐸✨🔬 By: Micaela Lasser, Helen Willsey Helen Willsey Lab ZEISS Microscopy LSM980

Brunch anyone?

DYK we can make frogs where just the right half of the animal carries a mutation of interest? Here the right eye has a CRISPR mutation in a gene required for eye pigment! By Helen Willsey (during postdoc with Richard Harland on a Leica Microsystems scope)

Check out this great new preprint discovering new developmental roles for Foxi1! 🤯

DYK we can make thousands of half-mutant (down the midline) embryos in Xenopus every day? One mating pair lays 4000+ embryos each day- inject whatever you like into 1 cell at the 2-cell stage and watch it be inherited into just one half of the 🐸!

Having fun CRISPRing frog embryos as part of Dev Bio Week in the MD Anderson-UTH Grad Core Course!

Munevver Burcu Cicekdal then used CRISPR-Cas9 in #Xenopus tropicalis 🐸 to disrupt just element CE14: loss of this element alone causes developmental eye anomalies similar to those seen in our case, as shown by these beautiful 3D images generated by Thomas Naert

Nothin better than coming back to a whole dish of ‘bros who’ve turned!

Happy Halloween to all the dev bio enthusiasts out there! We rep Hilde hard in the Helen Willsey household

Asking for an extension to your NIH grant ESI status is easy in eRA commons. Look into it! Lots of eligible reasons to extend, including having kids.
