Prediction of spatio-temporal bone formation in scaffold by diffusion equation

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Arne Christian Vogel, Alireza Roshan Ghias

Developing a successful bone tissue engineering strategy entails translation of experimental findings to clinical needs. A major leap forward towards this goal is developing a quantitative tool to predict spatial and temporal bone formation in scaffold. We ...

Mechanical interaction between cells and fluid for bone tissue engineering scaffold: modulation of the interfacial shear stress

Dominique Pioletti, Alexandre Terrier, Lalaonirina Rakotomanana Ravelonarivo, Luc Blecha

An analytical model of the fluid/cell mechanical interaction was developed. The interfacial shear stress, due to the coupling between the fluid and the cell deformation, was characterized by a new dimensionless number . For above a critical value, the flui ...

Targeted mechanical properties for optimal fluid motion inside artificial bone substitutes

Dominique Pioletti, Alexandre Terrier, Lalaonirina Rakotomanana Ravelonarivo, Luc Blecha

The goal of this study was to develop a method that identifies optimal elastic modulus, Poisson’s ratio, porosity and permeability values for mechanically stressed bone substitute. It was hypothesized that porous bone substitute that favors the transport o ...

Delay of intracortical bone remodelling following a stress change: a theoretical and experimental study

Alexandre Terrier, Lalaonirina Rakotomanana Ravelonarivo

BACKGROUND: A theoretical model and an experimental setup were specifically designed to identify and determine the delay of the cortical bone response (restricted to mineralization and demineralization) to a stress change. METHODS: The in vivo experiment c ...
