Research Abstract |
We showed that a high oxygen tension markedly prolonged the duration of osteoclast precursor formation in the presence of supporting cells, and also markedly and persistently increased the production of macrophage colony stimulating factor (M-CSF) by supporting cells. These findings could explain some part of pathophysiology in severe bone destruction or osteolysis accompanied with abundant blood vessel and numeraous osteoclasts seen in several pathological conditions such as rheumatoid arthritis (RA) and primary or metastatic tumors. We also showed that O_2 concentrations decreased depending of the depth in both 20 and 5% O_2 tension, so medium depth is one of critical conditions to study the relation of the cellular environment of pericellular oxygen tension and cell biology.
