| Abstract |
Bone morphogenetic protein-4 (BMP-4), a member of the transforming growth factor-beta superfamily, is capable of initiating differentiation of uncommitted mesenchymal cells into a chondro/osteogenic pathway. This study reports the effects of pentoxifylline (PTX), a nonspecific inhibitor of phosphodiesterases (PDEs), that causes elevation of the intracellular cyclic adenosine monophosphate (cAMP) level on the BMP-4-induced chondro/osteogenic differentiation of a mesenchymal cell line, C3H10T1/2; a bone marrow stromal cell line, ST2; and an osteoblastic cell line, MC3T3-E1. It was found that PTX enhanced BMP-4-induced chondro/osteogenic differentiation in C3H10T1/2 and ST2 cells. Similar effects were observed when adding dibutyryl-cAMP and forskolin. These results indicate that cAMP may potentiate the action of BMP-4 on osteoprogenitor cells, highlighting the possibility that PDE inhibitors could be used as therapeutic agents to enhance bone formation through this effect.
