[Evaluation of the biological compatibility of bioglass with a new experimental model, the fibronectin binding test]

The authors expose their results about the biological compatibility of Bioglass (BG), using a new experimental model; this model implicates the use of Fibronectin (FN), a glycoprotein involved in cellular adhesion. The term Bioglass indicates a family of glasses (of possible use as implants) with the formation of a stable calcium-phosphate film on their surface when in contact with an aqueous environment. Two types of BG, B5 and B6, have been incubated with FN; the first binds three times B6 the FN. The results are discussed considering other preliminary results.
