Physical constraints on accuracy and persistence during breast cancer cell chemotaxis
Julien Varennes, Hye-ran Moon, Soutick Saha +2
Directed cell motion in response to an external chemical gradient occurs in many biological phenomena such as wound healing, angiogenesis, and cancer metastasis. Chemotaxis is ofte…
Temporal precision of regulated gene expression
Shivam Gupta, Julien Varennes, Hendrik C. Korswagen +1
Important cellular processes such as migration, differentiation, and development often rely on precise timing. Yet, the molecular machinery that regulates timing is inherently nois…
Emergent versus Individual-based Multicellular Chemotaxis
Julien Varennes, Sean Fancher, Bumsoo Han +1
Multicellular chemotaxis can occur via individually chemotaxing cells that are mechanically coupled. Alternatively, it can emerge collectively, from cells chemotaxing differently i…
Collective chemotaxis through noisy multicellular gradient sensing
Julien Varennes, Bumsoo Han, Andrew Mugler
Collective cell migration in response to a chemical cue occurs in many biological processes such as morphogenesis and cancer metastasis. Clusters of migratory cells in these system…
Sense and sensitivity: physical limits to multicellular sensing, migration and drug response
Julien Varennes, Andrew Mugler
Metastasis is a process of cell migration that can be collective and guided by chemical cues. Viewing metastasis in this way, as a physical phenomenon, allows one to draw upon insi…
Electrical Contacts to Three-Dimensional Arrays of Carbon Nanotubes
Aron W. Cummings, Julien Varennes, François Léonard
We use numerical simulations to investigate the properties of metal contacts to three-dimensional arrays of carbon nanotubes (CNTs). For undoped arrays top-contacted with high or l…
