I am proud to have contributed to this project during the first part of my postbaccalaureate fellowship, and excited to spend the rest of my time in this lab further investigating this structure.

#KnowYourZDM: In 2019, a 10-year-old patient w/ a life-threatening lymphatic disorder was losing hope. Zebrafish to the rescue! Scientists created zebrafish with the same gene mutation and found a melanoma drug that fixed the fish. Then, doctors used the same drug on the patient to save his life! 🧪

#KnowYourZDM: Humans and #zebrafish carrying mutations in VEGFC or its receptor (FLT4) have defects in the formation of their lymphatic systems, which are important for draining lymph back into the circulation system.  As a result, these individuals display severe #lymphedema. 🧪

Our latest preprint! Into morphogenesis, Yap, ECM, signaling, vertex models, feedbacks/robustness? There is something here for everyone. We discovered a positive feedback loop that extends inner ear canals, and a built-in mechanism that shuts it down when morphogenesis is done. tinyurl.com/464wsjhd

Cancer cells are notoriously plastic, but what triggers the changes in cell state? In our new Nature (@nature.com)‬ paper, Miranda Hunter (@mrndhntr.bsky.social‬) found that mechanical pressure is a key to this switch. Check it out here: go.nature.com/47iwDm2

Happy to see our work, led by @ivanbassi.bsky.social, out today in @jem.org! #Zebrafish help us find new treatments for a #rare_disease affecting #lymphatic vessels! Congrats to all authors and thanks to #MDBRide4Rare, #ODC_UPenn, @erc.europa.eu for support @weizmanninstitute.bsky.social

Check this neuron infected with #SARSCoV2 being attacked by a microglia. Is this process beneficial or detrimental? Do we want therapies to inhibit microglia activation/neuroinflammation, but what if it means more neurons infecting other neurons? Neurovirology is fascinating! #FluorescenceFriday

mRNA tech is some of the coolest, most powerful, most promising scifi shit humans are currently doing. They are being investigated to help with cancers, autoimmune diseases, M.S., stroke recovery, heart disease, diabetes, arthritis, and high cholesterol.

New short story from my postdoc in the Bassler lab is up on bioRxiv! Turns out our favorite quorum sensing responsive phage VP882 is a member of a larger family of phages that is distributed across multiple bacterial species and can eavesdrop on a universally conserved autoinducer. #PhageSky 🦠🧫

Hey friends - Daniocell is experiencing a temporary outage right now. The NICHD server it is hosted on got dropped from the NIH’s firewall list & so currently can’t be accessed outside the NIH. The relevant IT teams are working to resolve it. Sorry for any inconvenience. It’ll be back soon!!

I doubt that there is a single family in America that hasn’t benefitted directly from the NIH.

💥 Paper accepted (in principle) #cellfie 🤩 A long wait, a beautiful project, some amazing collaborations. Stay tuned for more ! ALT : how cells (and cell-like beads) are deformed in constraining vessels

Our latest issue is now live! On the cover is a species of Asian noodlefish characterized by their transparency due to the absence of red blood cells, slender bodies and scaleless skins, and a poorly ossified skeleton. www.cell.com/current-biol...

I might be a bit obsessed with blood vessels in the brain 🤓! Aren't they pretty? And check the red blood cells inside the small ones! Is it okay if I keep advertising our call for papers using more images of blood vessels in the brain? 😜🔬 #dementia #WomenInStem With @natureportfolio.nature.com

Two great new #Zebrafish preprints from the #WeinsteinLab using a new transgenic that reports epigenetic silencing and activation! Great to study epigenetic changes in vertebrates, and we even did an ENU screen. Excellent work by @mmarvel.bsky.social et al. 🧪 www.biorxiv.org/content/10.1...
