Bioresorbable Phosphate Scaffolds for Bone Regeneration
In this work, a new bioresorbable phosphate glass (I-CEL2) was prepared in order to use it for the production of 3D-bioresorbable scaffold for bone regeneration. I-CEL2 was characterized to assess its thermal characteristics as well as its bioresorption rate in different medium such as distilled water, Tris-HCl and Simulated Body Fluid (SBF). 3D-macroporous scaffolds were prepared by mixing and pressing I-CEL2 powders and an organic phase and by treating the compact of powders at 550°C for 3 hours. The obtained scaffolds showed a very high porosity and a high resorption rate and are thus suitable candidates for a scaffold to be used as a temporary guide for bone regeneration. The initial response of human marrow stromal cells (hMSCs) has been tested on I-CEL2 surface to describe its biological potential.
