Primary data for EPFL thesis "Characterisation of conditional alleles of the Schizosaccharomyces pombe cytokinesis regulator byr4"

Regulation of cytokinesis is essential for the cell during its division cycle. Failure to do so can lead to aneuploidy, which can be fatal and lead to senescence or cancer. A useful model organism for studying cytokinesis in eukaryotes is Schizosaccharomyc ...

Structures of SAS-6 coiled coil hold implications for the polarity of the centriolar cartwheel

Pierre Gönczy, Georgios Hatzopoulos

Centrioles are eukaryotic organelles that template the formation of cilia and flagella, as well as organize the microtubule network and the mitotic spindle in animal cells. Centrioles have proximal-distal polarity and a 9 fold radial symmetry imparted by a ...

Integrative approach to analyze the proximal region of the Trichonympha agilis centriole

Veronika Nemcíková Villímová

The centrosome, the major microtubule organizing center in animal cells, is composed of two orthogonally arranged centrioles and surrounding pericentriolar material. Centrioles are evolutionary conserved organelles characterized by a nine-fold symmetry of ...

A comparison of orbitally-shaken and stirred-tank bioreactors: pH modulation and bioreactor type affect CHO cell growth and protein glycosylation

Florian Maria Wurm, Lucia Baldi Unser, David Hacker, Marc Moniatte, Valentin Juvet, Dominique Terry Monteil Jr

Orbitally shaken bioreactors (OSRs) support the suspension cultivation of animal cells at volumetric scales up to 200 L and are a potential alternative to stirred-tank bioreactors (STRs) due to their rapid and homogeneous mixing and high oxygen transfer ra ...

Protrusion-retraction switches and traction forces in spontaneous cell polarization

Alicia Carine Bornert

Cell migration is a fundamental property of all animal cells which is involved in processes such as embryogenesis, immune response, tissue regeneration and cancer metastasis. Directional migration requires cell polarization which could happen in response t ...

Chemical Genetic Screen Identifies Natural Products that Modulate Centriole Number

Kai Johnsson, Pierre Gönczy, Zhou Fang, Michele Graciotti

Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...

Purification of centrosomes from mammalian cell lines

Paul Guichard

Centrosomes act as the main microtubule-organizing centre of animal cells and play critical roles in the cell, such as mitotic spindle organization, cell polarity, and motility. They are composed of two barrel-shaped structures, the centrioles, surrounded ...
