Vitamin D deficiency elicits hypocalcified dentin. However, little is known about the action of vitamin D on the syntheses of dentin matrix proteins. In this study, we examined the effects of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] on the expressions of osteocalcin and osteonectin/secreted protein, acidic and rich in cysteine (SPARC), by human pulp cells in the presence or absence of transforming growth factor-β1 (TGF-β1) or basic fibroblast growth factor (bFGF). 1,25(OH)2D3 markedly increased osteocalcin at protein and mRNA levels. The osteocalcin level induced by 1,25(OH)2D3 was decreased and increased by TGF-β 1 and bFGF, respectively. 1,25(OH)2D3 suppressed SPARC synthesis at protein and mRNA levels. TGF-β1, but not bFGF, increased SPARC synthesis in the presence of 1,25(OH)2D 3. SPARC, but not osteocalcin, increased DNA synthesis in pulp cells. These findings suggest that 1,25(OH)2D3 and growth factors interactively regulate the expression of osteocalcin and SPARC in pulp cells, and that SPARC can stimulate DNA synthesis by pulp cells.
