Effects of dynamic environments on extracellular morphogen gradients

Mark Fleury

Tissue morphogenesis and remodeling is often orchestrated by cell-secreted proteins, referred to as morphogens that can trigger cellular responses in addition to modifying the local extracellular matrix (ECM). Of specific interest is the distribution of ce ...

Autologous chemotaxis as a mechanism of tumor cell homing to lymphatics via interstitial flow and autocrine CCR7 signaling

Melody Swartz, Alice Anna Tomei, Mark Fleury, Carolyn Yong Pullin

CCR7 is implicated in lymph node metastasis of cancer, but its role is obscure. We report a mechanism explaining how interstitial flow caused by lymphatic drainage directs tumor cell migration by autocrine CCR7 signaling. Under static conditions, lymphatic ...

Effects of extracellular fiber architecture on cell membrane shear stress in a 3D fibrous matrix

Melody Swartz

Interstitial fluid flow has been shown to affect the organization and behavior of cells in 3D environments in vivo and in vitro, yet the forces driving such responses are not clear. Due to the complex architecture of the extracellular matrix (ECM) and the ...

Multiscale modelling of metabolism and transport phenomena in living tissues

Carlo D'Angelo

The range of applications of mathematical modelling in biosciences has recently expanded to encompass problems posed by biomedicine and sport sciences. Topics of interest are for instance the prediction of the response of an athlete to exercise, the pharma ...

Characterization of lymphangiogenesis in a model of adult skin regeneration

Melody Swartz

To date, adult lymphangiogenesis is not well understood. In this study we describe the evolution of lymphatic capillaries in regenerating skin and correlate lymphatic migration and organization with the expression of matrix metalloproteinases (MMPs), immun ...

A sensitive in vivo model for quantifying interstitial convective transport of injected macromolecules and nanoparticles

Melody Swartz

Effective interstitial transport of particles is necessary for injected drug/diagnostic agents to reach the intended target; however, quantitative methods to estimate such transport parameters are lacking. In this study we develop an in vivo model for eval ...

Mechanisms of interstitial flow-induced remodeling of fibroblast-collagen cultures

Melody Swartz

Interstitial fluid flow, critical for macromolecular transport, was recently shown to drive fibroblast differentiation and perpendicular cell and matrix alignment in 3D collagen cultures. Here we explore the mechanisms underlying this flow-induced cell and ...
