Towards a physical understanding of developmental patterning

Andrew Charles Oates, Jose Negrete Jr

The temporal coordination of events at cellular and tissue scales is essential for the proper development of organisms, and involves cell-intrinsic processes that can be coupled by local cellular signalling and instructed by global signalling, thereby crea ...

Theory of time delayed genetic oscillations with external noisy regulation

Andrew Charles Oates, Laurel Ann Rohde, Jose Negrete Jr

Video Abstract Video Abstract: Theory of time delayed genetic oscillations with external noisy regulation We present a general theory of noisy genetic oscillators with externally regulated production rate and multiplicative noise. The observables that char ...

Mechanotaxis directs Pseudomonas aeruginosa twitching motility

Lorenzo Anton-Louis Talà, Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jose Negrete Jr, Marco Julian Kühn, Joanne Netter Engel

The opportunistic pathogen Pseudomonas aeruginosa explores surfaces using twitching motility powered by retractile extracellu-lar filaments called type IV pili (T4P). Single cells twitch by sequen-tial T4P extension, attachment, and retraction. How single ...

Receptor-induced transient responses in cells with oscillatory actin dynamics

Jose Negrete Jr

Living cells adjust their sensing and migratory machinery in response to changes in their environment. In this work, we show that cells of the social amoeba Dictyostelium discoideum modulate the dynamical state of their actin cytoskeleton in response to an ...

Embryonic lateral inhibition as optical modes: An analytical framework for mesoscopic pattern formation

Andrew Charles Oates, Jose Negrete Jr

Cellular checkerboard patterns are observed at many stages of embryonic development. We study an analytically tractable model for lateral inhibition and show that the steady states are analogous to optical phonons at the Gamma point, which have the wave nu ...
