Endothelial Cell Swelling by Aldosterone
There is accumulating evidence that mineralocorticoids not only act on kidney but also on the cardiovascular system. We investigated the response of human umbilical venous endothelial cells (HUVECs) to aldoste...

Secretion Pores in Human Endothelial Cells during Acute Hypoxia
Weibel-Palade bodies (WPB) are endothelial vesicles that store von Willebrand factor (vWF), involved in the early phase of hemostasis. In the present study we investigated the morphodynamics of single WPB plas...

Volume dynamics in migrating epithelial cells measured with atomic force microscopy
Migration of transformed renal epithelial cells (transformed Madin-Darby canine kidney cells, MDCK-F cells) relies on the activity of a Ca2+-sensitive K+ channel (IK channel) that is more active at the rear end o...

ATP-Induced Shape Change of Nuclear Pores Visualized with the Atomic Force Microscope
Bidirectional transport of molecules between nucleus and cytoplasm through the nuclear pore complexes (NPCs) spanning the nuclear envelope plays a fundamental role in cell function and metabolism. Nuclear imp...

Molecular weights of individual proteins correlate with molecular volumes measured by atomic force microscopy
Proteins are usually identified by their molecular weights, and atomic force microscopy (AFM) produces images of single molecules in three dimensions. We have used AFM to measure the molecular volumes of a nu...

Imaging excised apical plasma membrane patches of MDCK cells in physiological conditions with atomic force microscopy
We combined the patch-clamp technique with atomic force microscopy (AFM) to visualize plasma membrane proteins protruding from the extracellular surface of cultured kidney cells (MDCK cells). To achieve molec...
