Catechins inhibit vascular endothelial growth factor production and cyclooxygenase-2 expression in human dental pulp cells

Aim To investigate the effect of catechins on vascular endothelial growth factor ( VEGF ) production and cyclooxygenase‐2 ( COX ‐2) expression in human dental pulp cells ( HDPC ) stimulated with bacteria‐derived factors or pro‐inflammatory cytokines. Methodology Morphologically fibroblastic cells established from explant cultures of healthy human dental pulp tissues were used as HDPC . HDPC pre‐treated with catechins, epigallocatechin‐3‐gallate...
