In decalcified (5% nitric acid) and undecalcified (glycol-methacrylate or resin embedded) routinely processed bone specimens osteoclasts against resorbing surfaces were identified with monoclonal antibodies directed against leucocyte common antigen (LCA) (PD7/26, 2B11), CD68 (KP1), and gpIIIa (Y2/51) but not against HLA-DR (CR3/43 and Ta11B5). Mononuclear cells on resorbing surfaces and occasional mononuclear cells against or near resting surfaces showed a similar pattern of reactivity. This study shows that immunohistochemistry is a sensitive and useful technique for identifying osteoclasts in routinely processed bone specimens. It also suggests a role for mononuclear cells (possibly pre-osteoclasts) in bone resorption.
在脱钙(5%硝酸)和未脱钙(乙二醇甲基丙烯酸酯或树脂包埋)的常规处理骨标本中,用针对白细胞共同抗原(LCA)(PD7/26、2B11)、CD68(KP1)和gpIIIa(Y2/51)的单克隆抗体鉴定了与吸收表面相对的破骨细胞,但未鉴定出与HLA-DR(CR3/43和Ta11B5)相对的破骨细胞。吸收表面的单核细胞以及偶尔与静止表面相对或靠近静止表面的单核细胞显示出相似的反应模式。本研究表明,免疫组织化学是在常规处理骨标本中鉴定破骨细胞的一种敏感且有用的技术。它还提示单核细胞(可能是破骨细胞前体细胞)在骨吸收中起作用。
