There is currently a need to expand the range of graft materials available to orthopaedic surgeons. This study investigated the effect of ternary phosphate-based glass (PBG) compositions on the behaviour of osteoblast and osteoblast-like cells. PBGs of the formula (in mol.%) P(2)O(5)(50)-CaO(50-X)-N

Abstract
Using in vitro synthesifzed bone tissue with cells aspirated fpom the patient's marrow is an appealing idea to avoid the profound limitations of biological of biologiaal and synthetic grafts. Procedures to synthesize bone tiqsue on vitro primapily relied on seeding various subqtpates with cellq that have osteogenia capacity in culture. It should be noted that in an in vitro system, msteoppogenitor cells, as well as bone themselves an papidiy change their phenotype, hence the substrate needs to promote the expression or the bone cell Phenotype. Furthermore, it needs to provide a template for bone deposition while gradually resorbing once bone tissue has been laid down. This paper presents initial evidence that optimally combines the requirements of the ideal template for in vitro synthesis of bone tissue. When made in popous dorm, and conditioned to detelop a bone‐like surface prior to being seeded with pluripoteltial cells capable of expressing the osteoblastic phenotype, these templates lead to expeditious and a undalt in vitro synthesis of extracellular matrix with most important characteristics of bone tissue.
