Here it is! PPIL4, a new gene associated with Intracranial Aneurysms in humans, a new Wnt-mechanism of brain arteries formation, a step forward to understand this disease! So proud of everyone that worked on this project! nature.com/articles/s4159…

Great to see #zebrafish taking the center stage! Awesome collaboration! Thanks! Lukasz Bugaj

Excited to share our latest research on shear stress regulated endothelial enhancers in Scientific Reports. Great collaboration with the Schnittler laboratory, Vaquerizas Lab and The Arany lab! rdcu.be/cJtta

Happy to share out latest paper on vascular mural cells in developing and regenerating zebrafish fin arteries out in Development. Congratulations to the first author Elvin Leonard for the great work. journals.biologists.com/dev/article/do…

New findings often come unexpectedly! A large extracellular protein produced by non vascular cells cooperates with blood flow to stabilize new vessel connections! Delighted to share and discuss this with you. Great collaboration with Stefan Schulte-Merker!

Looks pretty awesome! Congratulations on the nice achievement.

Wow! After a long covid slumber, third paper out within 2 weeks! Congratulations to the first author Martin Lange and our collaborators from the Rui Benedito lab! Zebrafish mutants in vegfab can affect endothelial cell proliferation ... sciencedirect.com/science/articl…

Siekmann lab reunion IVBM2022. Having fun with Zeenat Diwan, Elvin Leonard, Martin Lange and Sana Hasan.

Join us THIS THURSDAY Dec 15th at 1PM EST for InFocus Session: Vascular Malformations. Trainee speakers were chosen from Abstracts submitted to #IVBM2022. These sessions are NOT recorded so don't miss out!! Register now- These sessions are free to ALL! conta.cc/3uQUNzf

Happy to announce that our latest paper on fin blood vessel development is online now: journals.biologists.com/dev/article/do… Congratulations to Elvin Leonard and Sana S. Hasan for the amazing work!

This #FluorescenceFriday we highlight the forming vasculature in a zebrafish fin. Research from Elvin Leonard, Sana Hasan & Siekmann Lab reveals the existence of distinct morphogenetic processes that generate the mature fin vasculature. 📖Development: journals.biologists.com/dev/article/15…

Very happy to share that Arndt just got tenure at UPenn! Thanks a lot to all previous and current members of the lab for their great work and enthusiasm to make this happen. Enjoying hot pot with the lab to celebrate!

Enjoying a great meeting in Barcelona! #evbo

Happy to share out latest review article on Vascular Mural Cells published in Development ! journals.biologists.com/dev/article-ab…

Happy to share our latest results on arteriovenous malformations! Congratulations to PhD student Zeenat Diwan Zeenat Diwan for her great work! Alk1/Endoglin dependent increases in vein endothelial cell sizes precipitate arteriovenous malformations biorxiv.org/content/10.110…

Congratulations Zeenat Diwan for successfully defending her PhD CAMB Graduate Group! Well deserved!!

Arndt will be speaking at 18th International Zebrafish Conference. Please check out my talk if you're attending the event! #IZFC2024 - via #Whova event app

Happy to share Zeenat's paper in Angiogenesis on differences between arterial and venous cell sizes and the specific role of endoglin signaling in veins! Great job! link.springer.com/10.1007/s10456…
