This study developed highly porous degradable composites as potential scaffolds for bone tissue engineering. These scaffolds consisted of poly-D,L-lactic acid filled with 2 and 15 vol.% of 45S5 Bioglass particles and were produced via thermally induced solid-liquid phase separation and subsequent solvent sublimation. The scaffolds had a bimodal and anisotropic pore structure, with tubular macro...

The effect of the ionic products of Bioglass 45S5 dissolution on the gene-expression profile of human osteoblasts was investigated by cDNA microarray analysis of 1,176 genes. Treatment with the ionic products of Bioglass 45S5 dissolution increased the levels of 60 transcripts twofold or more and reduced the levels of five transcripts to one-half or less than in control. Markedly up-regulated ge...

Scaffolds of PDLLA were produced to be implemented in maxilofacial surgeries inducing bone repair and regeneration. To prepare these scaffolds, bioglass (BG58S) was synthesized by sol-gel method, in order to be applied as osteoconductive dispersed particles in PDLLA matrix. Once presenting greater facility on parts fabrication, this polymeric matrix enables complex geometries production besides...
