A novel microfluidics-based bilayer device with a discrete parenchymal chamber modeled upon hepatic organ architecture is described. The microfluidics network was designed using computational models to provide appropriate flow behavior based on physi

One of the principal challenges facing the field of tissue engineering over the past 2 decades has been the requirement for large-scale engineered constructs comprising precisely organized cellular microenvironments. For vital organ assist and replac

This paper presents a finite element formulation suitable for large-strain modeling of biological tissues and uses this formulation to implement an accurate finite element model for mitral valve leaflet tissue. First, an experimentally derived strain

Mass transport may play a significant role in the development of atherosclerosis, a progressive disease of the artery wall. In this work, advection-dominated transport of blood-borne components such as oxygen and ATP is considered in two arterial mod

Living cells respond to mechanical stimulation in a variety of ways that affect nearly every aspect of their function. Such responses can range from changes in cell morphology to activation of signaling cascades and changes in cell phenotype. Althoug

Large-strain constitutive modeling of biological tissues has grown enormously as a field in the past decade. This paper investigates the viability of the existing models for describing heart valve leaflet mechanics. The properties of the leaflet tiss

Vascular endothelial cells rapidly transduce local mechanical forces into biological signals through numerous processes including the activation of focal adhesion sites. To examine the mechanosensing capabilities of these adhesion sites, focal adhesi

Atherogenesis is known to be associated with the stresses that act on or within the arterial wall. Still, the uneven distribution of atherosclerotic lesions and the impact of vessel remodeling on disease progression are poorly understood. A methodolo
