In vivo cyclic loading as a potent stimulatory signal for bone formation inside tissue engineering scaffolds

Dominique Pioletti, Pierre-Etienne Bourban, Alexandre Terrier, Alireza Roshan Ghias

In clinical situations, bone defects are often located at load bearing sites. Tissue engineering scaffolds are future bone substitutes and hence they will be subjected to mechanical stimulation. The goal of this study was to test if cyclic loading can be u ...

Solidification Behaviour Of PLLA/nHA Nanocomposites

Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

PLLA crystallization rates increase with nHA content owing to increased nucleation, which compensates a decrease in spherulite growth rate, G, at 100 to 130 °C, and to suppression of the twin peak in G(T) seen in pure PLLA, linked to a transition from the ...
