Investigating Focal Adhesion Substructures by Localization Microscopy

Aleksandra Radenovic, Daniel Sage, Lely Feletti, Hendrik Georges Deschout

Cells rely on focal adhesions (FAs) to carry out a variety of important tasks, including motion, environmental sensing, and adhesion to the extracellular matrix. Although attaining a fundamental characterization of FAs is a compelling goal, their extensive ...

Combining PALM and SOFI for quantitative imaging of focal adhesions in living cells

Theo Lasser, Aleksandra Radenovic, Lely Feletti, Tomas Lukes, Hendrik Georges Deschout, Azat Sharipov

Focal adhesions are complicated assemblies of hundreds of proteins that allow cells to sense their extracellular matrix and adhere to it. Although most focal adhesion proteins have been identified, their spatial organization in living cells remains challen ...

Cellular forces and matrix assembly coordinate fibrous tissue repair

Mahmut Selman Sakar, Daniel Eberli

Planar in vitro models have been invaluable tools to identify the mechanical basis of wound closure. Although these models may recapitulate closure dynamics of epithelial cell sheets, they fail to capture how a wounded fibrous tissue rebuilds its 3D archit ...

Complementarity of PALM and SOFI for super-resolution live-cell imaging of focal adhesions

Theo Lasser, Aleksandra Radenovic, Lely Feletti, Marcel Leutenegger, Daniel Pawel Szlag, Tomas Lukes, Hendrik Georges Deschout, Azat Sharipov

Live-cell imaging of focal adhesions requires a sufficiently high temporal resolution, which remains a challenge for super-resolution microscopy. Here we address this important issue by combining photoactivated localization microscopy (PALM) with super-res ...

Proteolytic processing of the synaptic cell adhesion molecule neurexin-3beta and the neurobiological functions of the resulting cleavage products

Magda Maria Palczynska

Neurexins are key synaptic cell adhesion molecules involved in synapse specification and maturation. They couple synaptic activity and cell adhesion to regulate activity-dependent synapse development. Recently, neurexin processing by alpha- and gamma- secr ...

Fibroblast adhesion on ECM-derived peptide modified poly(2-hydroxyethyl methacrylate) brushes: Ligand co-presentation and 3D-localization

Harm-Anton Klok, Solenne Desseaux

Polymer brushes prepared via surface-initiated polymerization of 2-hydroxyethyl methacrylate are powerful platforms for the fabrication of model biointerfaces to study cell-substrate interactions. In this manuscript, the versatility of surface-initiated po ...

Force transmission during adhesion-independent migration

Andrew Charles Oates

When cells move using integrin-based focal adhesions, they pull in the direction of motion with large, â 1/4100 Pa, stresses that contract the substrate. Integrin-mediated adhesions, however, are not required for in vivo confined migration. During focal ad ...

Cell-mediated Fibre Recruitment Drives Extracellular Matrix Mechanosensing in Engineered Fibrillar Microenvironments

Mahmut Selman Sakar

To investigate how cells sense stiffness in settings structurally similar to native extracellular matrices, we designed a synthetic fibrous material with tunable mechanics and user-defined architecture. In contrast to flat hydrogel surfaces, these fibrous ...

Mechanical properties of peripheral stress fibers in adherent cells spreading on patterned substrates

Céline Jeanne Labouesse

Many cellular processes require or depend on mechanical feedback from the cell's micro-environment. For example, the local organization of the actin cytoskeleton is known to adapt to the physical properties of the extracellular matrix. To gain better under ...

DESIGN, FABRICATION, AND CHARACTERIZATION OF AFM TIPS FOR TENSIONS MEASUREMENT AND MANIPULATION OF FLUID INTERFACES

Marta Jole Ildelfonsa Airaghi Leccardi

Dynamic wetting phenomena lack of a proper qualitative and quantitative characterization, especially at the micro and nanoscale. The project focuses on the design and fabrication of AFM tips capable of measuring forces and energies involved in wetting phen ...
