巨噬细胞集落刺激因子(M-CSF)是破骨细胞和巨噬细胞从一个共同的骨髓前体分化所必需的。通过ST-2基质细胞/小鼠骨髓共培养,我们研究了增加M-CSF量对巨噬细胞和破骨细胞分化的影响。外源性M-CSF的添加导致酒石酸抗性酸性磷酸酶(TRAP)阳性多核细胞的剂量依赖性减少98%,同时非特异性酯酶染色巨噬细胞增加2.5倍。观察到破骨细胞功能活性的类似下降,包括125i标记的降钙素结合和降钙素刺激的腺苷3',5'-环单磷酸腺苷(cAMP)的产生。外源性M-CSF在共培养中添加超过6天,抑制破骨细胞形成的能力下降,这表明M-CSF在破骨细胞分化的早期发挥作用,在破骨细胞形成的增殖阶段。同样,早期加入中和性抗m - csf抑制破骨细胞的形成,超过第9天效果逐渐减弱。这些结果表明,局部高浓度的M-CSF可能影响最终分化为巨噬细胞或破骨细胞的早期决定。
Macrophage colony-stimulating factor (M-CSF) is essential for differentiation of osteoclasts and macrophages from a common bone marrow precursor. Using ST-2 stromal cell/murine bone marrow coculture, we studied the effects of increasing amounts of M-CSF on differentiation of macrophages and osteoclasts. Addition of exogenous M-CSF caused a dose-dependent 98% decrease in tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells, accompanied by a 2.5-fold increase in nonspecific esterase-staining macrophages. Similar decrease in osteoclastic functional activity, including 125I-labeled calcitonin binding and calcitonin-stimulated adenosine 3',5'-cyclic monophosphate (cAMP) production, were observed. Addition of exogenous M-CSF beyond 6 days in coculture had a decreasing ability to inhibit osteoclast formation, suggesting that M-CSF exerts its effects early in osteoclast differentiation, during the proposed proliferative phase of osteoclast formation. Similarly, early addition of neutralizing anti-M-CSF inhibited osteoclast formation, with diminishing effects beyond day 9. These results suggest that local high concentrations of M-CSF may influence the early determination of terminal differentiation into either macrophages or osteoclasts.
