The chemical durability in Tris-HCl solution was increased with the increase in the niobium content in the glasses, since niobium replaced to phosphorus and contributed to the formation of P-O-Nb and Nb-O-Nb bonds, which are stronger than P-O-P bond. The niobium ions released from the glasses enhanced the differentiation and mineralization of the cells, rather than the initial adhesion and proliferation. The upregulation of these cell functions by the niobium ions possessed doze-dependence; the medium containing 1 x 10 M of the ions exhibited the highest levels of the cell functions.
