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…

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

Congratulations @Zeenat_JL for successfully defending her PhD @CAMBUpenn! Well deserved!!

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

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

Enjoying a great meeting in Barcelona! #evbo

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!

@wythelab @UVa_CellBio @uvamedicine Congratulations Josh! Wishing you a great start!

This #FluorescenceFriday we highlight the forming vasculature in a zebrafish fin. Research from @ElvinLeonard3, Sana Hasan & @SiekmannLab reveals the existence of distinct morphogenetic processes that generate the mature fin vasculature. 📖@Dev_journal: journals.biologists.com/dev/article/15…

Happy to announce that our latest paper on fin blood vessel development is online now: journals.biologists.com/dev/article/do… Congratulations to @ElvinLeonard3 and Sana S. Hasan for the amazing work!

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

Siekmann lab reunion @ivbm2022. Having fun with @Zeenat_JL, @ElvinLeonard3, Martin Lange and Sana Hasan.

Happy to share our results on zebrafish tail fin blood vessel expansion by @ElvinLeonard3 and Sana Hasan! Fascinating to compare to work by @ScottPaulissen from the Weinstein lab, @Rudra_nayan from the @Yaniv_lab and Rosalind Bump from @jraslab! Similar, but different! So cool!

@PennCDB @buenoscience Congratulations Matt! Well deserved!

Congratulations to Matthew Good, PhD (@buenoscience) on his promotion to Associate Professor of Cell and Developmental Biology with tenure, an amazing achievement and milestone in his academic career!

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

Looks pretty awesome! Congratulations on the nice achievement.

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!

Happy to share out latest paper on vascular mural cells in developing and regenerating zebrafish fin arteries out in @Dev_journal. Congratulations to the first author @ElvinLeonard3 for the great work. journals.biologists.com/dev/article/do…

Excited to share our latest research on shear stress regulated endothelial enhancers in @SciReports. Great collaboration with the Schnittler laboratory, @vaquerizas_lab and @AranyLab! rdcu.be/cJtta
