Abstract:目的探讨Ca2+信号对1α,25-二羟维生素D3(1α,25-(OH)2D3)调控破骨细胞(osteoclast,OC)形成及骨吸收活性的影响。方法在巨噬细胞集落刺激因子(macrophage colony-stimulating factor,M-CSF)及核因子-κB受体活化因子配体(receptor activator of nuclear factor-κB ligand,RANKL)联合诱导RAW264.7细胞分化为OC的基础上,添加10-8 mol/L 1α,25-(OH)2D3,并设Ca2+螯合剂1,2-双(2-氨基苯氧基)乙烷-N,N,N`,N`-四乙酸四乙酸甲酯(BAPTA-AM)干预组,通过抗酒石酸酸性磷酸酶(TRAP)染色鉴定OC的形成,环境扫描电镜观察牛皮质骨片吸收陷窝。结果添加10-8 mol/L 1α,25-(OH)2D3可显著增加OC数量,促进骨吸收活性。然而,与添加10-8 mol/L 1α,25-(OH)2D3比较,5μmol/L BAPTA-AM干预可显著降低OC数量,抑制骨吸收活性。结论 10-8 mol/L 1α,25-(OH)2D3能够促进OC形成和骨吸收活性,此过程涉及Ca2+信号机制。
