AIM: To evaluate the effects of two types of calcium silicate cements on viability, angiogenic growth factor release, and angiogenic and inflammation-related gene expression in human stem cells from the apical papilla (SCAP).
METHODOLOGY: SCAPs were grown for 7 days with either ProRoot mineral trioxide aggregate (MTA) or Biodentine (BD). Cell viability and media concentrations of vascular endothelial growth factor (VEGF/VEGFA) and angiopoietin 1 (ANGPT1) were measured. The expression of genes related to angiogenic potential and inflammatory response was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). One-way and two-way analyses of variance with multiple comparisons Tukey's test were performed (P < 0.05).
RESULTS: Cells in contact with either cement were associated with increased cell viability compared with the no-treatment group at day 1 but there were no differences amongst groups at days 3 and 7. Exposure to either cement significantly increased VEGF concentrations at day 3; however, ANGPT-1 levels decreased significantly compared with the no-treatment group at day 3. Exposure to MTA and BD stimulated expression of VEGFA and FIGF/VEGFD. Furthermore, exposure to both cements significantly decreased the mRNA levels of ANGPT1 and FGF2 relative to the no-treatment group.
CONCLUSIONS: Both MTA and BD stimulated the expression of angiogenic genes and release of VEGF, inducing similar expression patterns; however, they appeared to inhibit the expression of specific genes, including ANGPT1 and FGF2.
