Vascular and Tumor Biology Lab @OncoUNILCHUV @unil. We study organ- and disease-specific functions of lymphatic and blood vessels.
Rockefeller U. Press @RockUPress.@JExpMed July issue is here! 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):
Journal of Cell Biology @JCellBiolSpotlight: Nicola Diny @UniklinikBonn previews a study from @petrovalab et al. ( which reveals that #eosinophils drive a developmental program for postnatal intestinal remodeling and maturation. #Development
Journal of Experimental Medicine @JExpMedIrena 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. #lymphatics #AQP1
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.
