在这项免疫细胞化学研究中,我们用两种不同的单克隆抗体探测了一些人骨细胞类型和骨制剂中雌激素受体(ER)的存在。使用经过充分验证的识别人ER的抗体(H222)和标准过氧化物酶抗过氧化物酶方法,我们无法在培养的原代或转化的人骨源性细胞或胎儿骨切片中证明ER的核染色。尝试使用银增强程序在骨肉瘤细胞系(TE 85 C和HTB 96)中可视化ER也不成功。此外,我们未能在对照或雌激素处理的人骨细胞培养物中检测到孕酮受体的免疫细胞化学染色(使用单克隆抗体mPR 1)。雌激素和孕激素受体染色在MCF 7人乳腺癌细胞中容易检测到。与此相反,与单克隆抗体,识别29 kDa的细胞质成分(p29)密切相关的人ER,我们观察到在所有的成骨细胞样细胞研究的特异性染色。这种p29抗原的细胞质染色在人骨源性细胞的原代培养物中最强烈。相对丰富但尚未确定的p29抗原可能作为细胞中ER存在的敏感标志物,其水平低于抗ER单克隆抗体的检测限。如果是这样的话,我们的结果是一致的,ER在成骨细胞样细胞在非常低的浓度存在。
In this immunocytochemical study we have probed a number of human bone cell types and bone preparations for the presence of the estrogen receptor (ER) with two distinct monoclonal antibodies. Using a well‐validated antibody (H222) that recognizes human ER and standard peroxidase‐antiperoxidase methodology, we were unable to demonstrate nuclear staining for ER in cultured primary or transformed human bone‐derived cells or in fetal bone sections. Attempts to visualize ER in osteosarcoma cell lines (TE85C and HTB96) using a silver enhancement procedure were also unsuccessful. Additionally, we failed to detect immunocytochemical staining for the progesterone receptor (using monoclonal antibody mPR1) in control or estrogen‐treated human bone cell cultures. Estrogen and progesterone receptor staining was readily detectable in MCF7 human breast cancer cells. In contrast, with a monoclonal antibody that recognizes a 29 kDa cytoplasmic component (p29) closely related to human ER, we observed specific staining in all the osteoblastlike cells studied. Cytoplasmic staining for this p29 antigen was most intense in primary cultures of human bone‐derived cells. It is possible that the relatively abundant but as yet undefined p29 antigen may act as a sensitive marker for the presence of ER in cells at levels below the detection limit of the anti‐ER monoclonal antibody. If so, our results are consistent with the presence of ER in osteoblastlike cells at very low concentrations.
