| Outline of Final Research Achievements |
TThis study was aimed to elucidate the effect of hydrogen sulfide on the differentiation mechanism of bone marrow stem cells. Bone marrow stem cells were isolated from mouse femur using stem cell separation device. CD114 (+) positive cells (BMC-CD117 (+)) were isolated from the stem cells using a Magnetic separation system . NFAT1 and Aggrecan Neoepitope were present in the BMC-CD117 (+). BMC-CD117 (+) were cultured for 3 days with hydrogen sulfide. Multinucleated cells of tartrate-resistant acid phosphatase-positive that is a differentiation marker of osteoclast were significantly observed. Hydrogen sulfide was induced differentiation of osteoclasts from bone marrow stem cells, suggesting that it is a risk factor for alveolar bone resorption.
