Abstract
CD109 antigen on the endothelial cell surface plays an important role in vascular pathology. The aim of the work was to investigate the effect of the immobilization of CD109 antigen with specific antibodies on nanomechanical properties of human umbilical endothelial cells (HUVECs) using atomic force microscopy in quantitative nanomechanical property mapping mode (PeakForce QNM). Anti-CD109 antibodies induced significant stiffening of the cell surface Me(LQ; UQ): in 1.45(1.07;2.29) times with respect to control cells for fixed cells and in 4.9(3.6;5.9) times with respect to control cells for living cells, and changes in the spatial distribution of cell surface mechanical properties. The changes in the HUVEC's mechanical properties were accompanied by the activation of the TGF-/Smad2/3 signaling pathway and reorganization of the vimentin and actin cytoskeletal elements. Our findings show that blocking CD109 antigen using anti-CD109 antibodies leads in HUVECs to the processes similar to that occur after cell TGF-β-signaling activation. Therefore, we suggest that CD109 antigen may be involved in regulating the mechanical behavior of endothelial cells.

Abstract
The Young's modulus of 10-12-day-old chick embryos' sensory neurons cultivated in dissociated cell culture was measured using a PeakForce Quantitative Nanomechanical Mapping atomic force microscopy. The native cells were tested in control experiments and after application of ouabain. At low "endogenous" concentration of 10⁻¹⁰ M, ouabain tended to increase the rigidity of sensory neurons. We hypothesize that this trend resulted from activation of Na⁺,K⁺-ATPase signal-transducing function.
