Crump Lab

@AkiUshiki @WashUGenetics Thanks for the invitation. It was wonderful meeting everyone!

Thank you for visiting St. Louis @CrumpLab! Learned a lot from the seminar and discussion. 🐟 🧬@WashUGenetics

@AkiUshiki I'm excited to visit soon!

Lab group photo!

1/9 Thrilled to share that our paper, “Origin of Ewing sarcoma by embryonic reprogramming of neural crest to mesoderm,” is now published in @CellReports! @amatrudalab.bsky.social @CrumpLab cell.com/cell-reports/f…

@V4Sdb @MarcelaBuchtova The hikes weren’t bad either

Wow, that was amazing! We thank everyone for attending the V4SDB 2025 meeting! You all made it an excellent conference, where we had the opportunity to hear from outstanding speakers,share ideas and experiences, and of course have some unforgettable time during social activities!

@V4Sdb @MarcelaBuchtova What a wonderful conference!

Meet USC’s CIRM Scholar Alumna Joanna Smeeton, Assistant Professor at Columbia University. @smeetonlab @USCStemCell @KeckSchool_USC @CrumpLab @cscicolumbia stemcell.keck.usc.edu/cirm-scholar-a…

Partnering with @USCStemCell and @CIRMnews to train the next generation of leaders in stem cell research. Since 2006, CIRM has supported 110 USC scholars who have gone on to drive innovation in academia, biotech, and patient care. bit.ly/4kH7e8j

While I’m a big fan of new technologies that help us study human biology…there’s still no replacement for animal research! I wrote an article outlining this in @GENbio genengnews.com/topics/transla…

$13.5 million from a CIRM Scholars program at @USCStemCell has supported and will support 110 trainees, including PhD students, postdocs and clinical trainees. They've had an outsized impact on the biomedical field. @cirmnews @KECKSchool_USC stemcell.keck.usc.edu/usc-trains-bio…

@evgenykvon @Nature Such a beautiful study. Congrats!

Our preprint describing the Range Extender element, which is required and sufficient for long-range enhancer activation at the Shh locus, is out in @Nature. nature.com/articles/s4158…

@martinperaJAX Exciting stuff!

Great write up from Mathi on her PhD journey @USCStemCell @KECKSchool_USC

The Society for Developmental Biology has released a statement on how the Abrupt Dismissal of NIH and NSF Staff Undermines Government Efficiency. bit.ly/3X9VEKd

@rrbehringer @SocDevBio @NIH @NSF Would love to have this as a poster! Reminds me of the butterfly alphabet I had as a kid.

Here is the 2025 embryo alphabet from alligator to zebrafish. Developmental biology is stunning & leads to important discoveries for human medicine. @SocDevBio @NIH @NSF

@rrbehringer @SocDevBio You saved the best for last!

Welcome to embryo alphabet. Each day I will post an unannotated embryo image. Today Z is for #zebrafish. Repost tweet w/an image of a different species embryo & add a quote including name that begins with same letter of the day. @SocDevBio

@martinperaJAX Thanks Martin!

Very cool study

Nice article in Scientific American about our work on outer ear evolution and a complimentary study from the lab of Maksim Plikus on role of unique lipids in mammalian ear cartilage. @MathiThiru95 @USCStemCell @KECKSchool_USC scientificamerican.com/article/our-ea…

@RicGottardi @Nature @MathiThiru95 Thanks Riccardo. Great to catch up and hear your seminar this week.

@CrumpLab @Nature @MathiThiru95 Such an amazing work, impressive discovery across species, and I loved to learn where our ears come from!

The outer ear is a mammalian innovation but where did it come from? In our study in @Nature, @MathiThiru95 and colleagues find that the outer ear arose from modification of an ancestral gill program first originating in marine invertebrates. nature.com/articles/s4158… 1/n

@Otola_ryntaro @Nature @MathiThiru95 Actually most of our lab's work focuses on the fish jawbones which are the evolutionary homologs of middle ear ossicles. This work on outer ear is new for us.

@CrumpLab @Nature @MathiThiru95 It's impressive. Beautiful work! Are you going to focus on ossicles? I'm so curious about how ossicles developed.
