Cell Biology and Biophysics Unit, European Molecular Biology Laboratory EMBL, Meyerhofstr 1, 69117 Heidelberg, Germany
J Cell Sci 124:978-87. 2011..Altogether, our data provide evidence that de novo Golgi biogenesis can occur in mammalian cells...
- Investigating relaxation processes in cells and developing organisms: from cell ablation to cytoskeleton nanosurgeryJulien Colombelli
Light Microscopy Group, Cell Biology and Biophysics Unit, European Molecular Biology Laboratory EMBL, D 69117 Heidelberg, Germany
Methods Cell Biol 82:267-91. 2007..By combining nanosurgery with fast live-imaging fluorescence microscopy, we show how the apparent equilibrium of the cytoskeleton can be perturbed regionally inside a cell...
- Mechanosensing in actin stress fibers revealed by a close correlation between force and protein localizationJulien Colombelli
Cell Biology and Biophysics, European Molecular Biology Laboratory EMBL, Meyerhofstrasse 1, D 69117 Heidelberg, Germany
J Cell Sci 122:1665-79. 2009..In summary, our quantitative analysis shows that force and protein localization are closely correlated in stress fibers, suggesting a very direct force-sensing mechanism along actin bundles...
