A very nice movie of HUVECs stained with our live cell actin probe SiR-actin. It compares YES kinase depletion by siRNA to a control siRNA in a collective migration assay.

Read more about YES kinase, its VE-Cad phosphorylation and endothelial adherens junctions in this very nice article in Nature Cardiovascular Research by the lab of Lena Claesson-Welsh:

Tyrosine-protein kinase Yes controls endothelial junctional plasticity and barrier integrity by regulating VE-cadherin phosphorylation and endocytosis - Nature Cardiovascular Research

Jin and coauthors show that Yes-mediated tyrosine phosphorylation is critical for VE-cadherin’s constitutive internalization and junctional pliability in endothelial cells, but it is not required for the induction of vascular leakage.

Cool article in Nature Physics by @IshiharaKsk & colleagues from Jülicher & Brugues labs in @mpicbg and Tanaka lab in IMP Vienna

In this study, Our live cell actin probe SiR-actin was used to image live neuroepithelial organoids growing for >50h.

Congratulations to the whole team!

Topological morphogenesis of neuroepithelial organoids - Nature Physics

During development, tissues with complex topology emerge from collections of cells with simple geometry. This process in neuroepithelial organoids is governed by two topologically distinct modes of epithelial fusion.
