A newly identified protein controls endothelial barrier function by acting as a cellular glue

The endothelial barrier function maintains vascular and tissue homeostasis, and therefore modulates many cardinal physiological processes such as angiogenesis, immune responses, and dynamic fluid exchanges throughout organs. Blood vessels rely on endothelial cell-cell adhesion to generate a

Cell vacuum: measuring micro-newton cell adhesion forces using micropipette suction

The force with which cells adhere to their substrate is of interest in the study of various diseases. For example, in the case of atherosclerosis, the disease that leads to heart attacks and strokes, the “leakiness” of

How can cancer cells use hydrogen peroxide to strive?

Hydrogen peroxide (H2O2) is a well-known antiseptic used in our homes since the 1920s. But did you know that our cells produce this molecule and that at low concentrations H2O2 instructs our cells to do different things,

Studying the interactions that trap cells in circulation

Healthy blood stem cells and invasive tumor cells use similar mechanisms to exit the circulatory system and penetrate other tissues. Cell migration is a multi-step process in which a number of adhesion molecules find their partners and
