ATP-dependent mechanics of red blood cells

T Betz, M Lenz, JF Joanny… - Proceedings of the …, 2009 - National Acad Sciences
Red blood cells are amazingly deformable structures able to recover their initial shape even
after large deformations as when passing through tight blood capillaries. The reason for this …

Equilibrium physics breakdown reveals the active nature of red blood cell flickering

…, NS Gov, C Sykes, JF Joanny, G Gompper, T Betz - Nature physics, 2016 - nature.com
Red blood cells, or erythrocytes, are seen to flicker under optical microscopy, a phenomenon
initially described as thermal fluctuations of the cell membrane. But recent studies have …

External forces control mitotic spindle positioning

J Fink, N Carpi, T Betz, A Bétard, M Chebah… - Nature cell …, 2011 - nature.com
The response of cells to forces is essential for tissue morphogenesis and homeostasis. This
response has been extensively investigated in interphase cells, but it remains unclear how …

[HTML][HTML] Active cell mechanics: Measurement and theory

WW Ahmed, É Fodor, T Betz - … et Biophysica Acta (BBA)-Molecular Cell …, 2015 - Elsevier
Living cells are active mechanical systems that are able to generate forces. Their structure
and shape are primarily determined by biopolymer filaments and molecular motors that form …

Cancer-associated fibroblasts lead tumor invasion through integrin-β3–dependent fibronectin assembly

…, M Pocard, P Mariani, N Elkhatib, T Betz… - Journal of Cell …, 2017 - rupress.org
Cancer-associated fibroblasts (CAFs) are the most abundant cells of the tumor stroma. Their
capacity to contract the matrix and induce invasion of cancer cells has been well …

Active diffusion positions the nucleus in mouse oocytes

…, WW Ahmed, M Bussonnier, P Mailly, T Betz… - Nature cell …, 2015 - nature.com
In somatic cells, the position of the cell centroid is dictated by the centrosome. The centrosome
is instrumental in nucleus positioning, the two structures being physically connected. …

Intracellular softening and increased viscoelastic fluidity during division

S Hurst, BE Vos, M Brandt, T Betz - Nature Physics, 2021 - nature.com
The life and death of an organism rely on correct cell division, which occurs through the
process of mitosis. Although the biochemical signalling and morphogenetic processes during …

Guiding neuronal growth with light

A Ehrlicher, T Betz, B Stuhrmann… - Proceedings of the …, 2002 - National Acad Sciences
Control over neuronal growth is a fundamental objective in neuroscience, cell biology,
developmental biology, biophysics, and biomedicine and is particularly important for the formation …

[HTML][HTML] Roadmap for optical tweezers

…, A Argun, TM Muenker, BE Vos, T Betz… - Journal of Physics …, 2023 - iopscience.iop.org
Optical tweezers are tools made of light that enable contactless pushing, trapping, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work by …

[HTML][HTML] Neurite branch retraction is caused by a threshold-dependent mechanical impact

K Franze, J Gerdelmann, M Weick, T Betz, S Pawlizak… - Biophysical journal, 2009 - cell.com
Recent results indicate that, in addition to chemical cues, mechanical stimuli may also impact
neuronal growth. For instance, unlike most other cell types, neurons prefer soft substrates. …
