| Abstract |
Although histological studies have suggested that endothelial cells in bone (BDECs) are associated with some osteolytic bone diseases, it is still unclear how BDECs contribute to bone remodeling. Here we examined the response of BDECs to basic fibroblast growth factor (bFGF, FGF-2) using primary and cloned murine BDECs isolated from the femurs of BALB/c mice. Treatment of primary and cloned BDECs with bFGF induced cyclooxygenase-2 (COX-2) mRNA and protein expression. Furthermore, bFGF promotes the production of prostaglandin E2 (PGE2), which is known to be a potent stimulator of bone resorption and to induce osteoclast formation. Because the secretion of PGE2 was suppressed by COX-2 specific inhibitor NS-398 and by COX-2 antisense oligodeoxynucleotides, bFGF promotes the synthesis of PGE2 in a COX-2-dependent manner. Therefore, endothelial cells in bone are associated with bone remodeling by controlling COX-2 expression and consequently PGE2 production. |
