Hydrodynamic theories of chemotaxis-driven invasion in proliferating cell populations
Giulia L. Celora, Martina Conte
Biased migration up chemical gradients and proliferation are fundamental drivers of collective invasion in several biological processes ranging from embryonic morphogenesis to canc…
Coupled chemotactic fronts in heterogeneous sensor-consumer cell mixtures
Marjorie Watts, Carles Falcó, Giulia L. Celora
Chemotaxis underlies the collective migration of cell populations in developmental processes and immune responses. While the theoretical investigation of single-cell-type collectiv…
A nonlinear theory for chemotactic fronts of mixed populations
Giulia L. Celora, Marjorie Watts, Carles Falcó +1
Collective migration of heterogeneous cell populations is central to many biological and physiological processes, including development and immune response. Recent experimental and…
Chemotaxis of cell aggregates: morphology and dynamics of migrating active droplets
Giulia L. Celora, Benjamin J. Walker, Mohit P. Dalwadi +1
Biological tissues have been observed to display emergent fluid-like properties, owing to physical interactions between cells. However, it remains unclear in general how these flui…
The diffusive dynamics and electrochemical regulation of weak polyelectrolytes across liquid interfaces
Giulia Laura Celora, Ralf Blossey, Andreas Munch +1
We propose a framework to study the spatio-temporal evolution of liquid-liquid phase separation of weak polyelectrolytes in ionic solutions. Unlike strong polyelectrolytes, which c…
Counterion-controlled phase equilibria in a charge-regulated polymer solution
Giulia L. Celora, Ralf Blossey, Andreas Münch +1
We study phase equilibria in a minimal model of charge-regulated polymer solutions. Our model consists of a single polymer species whose charge state arises from protonation-deprot…
Minimal Morphoelastic Models of Solid Tumour Spheroids: A Tutorial
Benjamin J. Walker, Giulia L. Celora, Alain Goriely +2
Tumour spheroids have been the focus of a variety of mathematical models, ranging from Greenspan's classical study of the 1970s through to contemporary agent-based models. Of the m…
The electric double layer at the interface between a polyelectrolyte gel and salt bath
Matthew G. Hennessy, Giulia L. Celora, Andreas Münch +2
The electric double layer (EDL) that forms at the interface between a polyelectrolyte gel and a salt bath is studied using asymptotic and numerical methods. Specifically, matched a…
Spatio-temporal modelling of phenotypic heterogeneity in tumour tissues and its impact on radiotherapy treatment
Giulia L. Celora, Helen M. Byrne, P. G. Kevrekidis
We present a mathematical model that describes how tumour heterogeneity evolves in a tissue slice that is oxygenated by a single blood vessel. Phenotype is identified with the stem…
A kinetic model of a polyelectrolyte gel undergoing phase separation
Giulia L. Celora, Matthew G. Hennessy, Andreas Münch +2
In this study we use non-equilibrium thermodynamics to systematically derive a phase-field model of a polyelectrolyte gel coupled to a hydrodynamic model for a salt solution surrou…
The dynamics of a collapsing polyelectrolyte gel
Giulia L. Celora, Matthew G. Hennessy, Andreas Münch +2
We analyse the dynamics of different routes to collapse of a constrained polyelectrolyte gel in contact with an ionic bath. The evolution of the gel is described by a model that in…
Phenotypic variation modulates the growth dynamics and response to radiotherapy of solid tumours under normoxia and hypoxia
Giulia L. Celora, Helen M. Byrne, Christos Zois +1
In cancer, treatment failure and disease recurrence have been associated with small subpopulations of cancer cells with a stem-like phenotype. In this paper, we develop and investi…
