Study of in vitro degradation of brushite cements scaffolds.

An interest path to fabricate supports for tissue engineering is to foam calcium phosphate cement's pastes leading to an increase on material's total porosity and interconnectivity which facilitates cells' adhesion, proliferation and differentiation. The aim of this work is to develop scaffolds of brushite cement and to evaluate its in vitro degradation rate. Macroporosity was obtained by foaming the liquid phase with different non-ionic surfactants (Tween 80 and Lutensol ON-110).
