.@JExpMed July issue is here! https://t.co/X7xQztVSH0 Roci et al. @petrovalab demonstrate that lymphatic endothelial cells require the water channel AQP1 for stress-adaptive lymphangiogenesis. This confocal image captures that dependency directly (1/2): https://t.co/R4AzGZXH5f

Thank you very much Nicola Diny and @JCellBiol for highlighting our work on intestinal eosinophils !🙏

[Journal of Cell Biology @JCellBiol]

Spotlight: Nicola Diny @UniklinikBonn previews a study from @petrovalab et al. (https://t.co/IibXY0JMPv) which reveals that #eosinophils drive a developmental program for postnatal intestinal remodeling and maturation. https://t.co/5mUcOiCKpz

Our new paper is live❣️🎊🎉🍾

[Journal of Experimental Medicine @JExpMed]

Irena Roci et al. @PetrovaLab show that the water channel AQP1 sustains lymphatic endothelial cell migration under osmotic stress, establishing tissue #osmolarity as a key biophysical determinant of postnatal #lymphangiogenesis. https://t.co/MPph4059oA

@HaoYin20 @JBernierLatmani Thank you 😊

Our new paper is out ! Congrats to @JBernierLatmani and the entire team!🎉🎉

[Journal of Cell Biology @JCellBiol]

#Eosinophils–usually linked to infection and disease–are actually helping to build the gut. New research from @PetrovaLab & @JBernierLatmani shows they reprogram fibroblasts into villus smooth muscle cells, helping shape and mature the villi postnatally. https://t.co/tw24ZaFYVC

EVBO Awards at GRC Lymphatics 2026

EVBO members Claudia Carlantoni and Stefanie Bobe were awarded an award for their outstanding poster presentations at the 2026 GRC Lymphatics conference!

Congratulations!

The conference took place in Lucca, Italy.

[Petrova Lab – Vascular and Tumor Biology @PetrovaLab]

From breakthroughs in human genetics to strategies for drug delivery via and to the lymphatic system - last day at GRC Lymphatics 2026 was a blast!
Congrats to everyone for making this conference a success! 🙌
See you in 2028 as we pass the torch to @KarinaYaniv & Mark Kahn!

[Petrova Lab – Vascular and Tumor Biology @PetrovaLab]

Wednesday - Day 4 of the GRC Lymphatics 2026!
More big topics on the table today:
- Lymphatics & cancer
- Immunological surveillance of tissues via lymph
- Lymphatic endothelium as active player in immunity

Lots of hard work ...and also a bit of play. 😄

[Petrova Lab – Vascular and Tumor Biology @PetrovaLab]

🤩Two more exciting days at GRC Lymphatics 2026!
We’re exploring big questions:
-Developmental origins of lymphatics
-Lymphatic mechanotransduction
-Organ‑specific lymphatics and new therapies
Looks like an incubator for many new collaborations!

[Petrova Lab – Vascular and Tumor Biology @PetrovaLab]

🚀GRC Lymphatics 2026 kicked off! 🚀
Great mix of old and new friends, many exciting new results - amazing to see the field growing.
Chair & co-chair in the pic. Very sorry Brant Weinstein and Karina Yaniv @KarinaYaniv aren’t here - we miss you!
