基底细胞癌(BCC)中基底膜带(BMZ)成分发生改变。电子显微镜已在人BCC中鉴定出正常、不连续或不存在BMZ组分的区域[13,15,26]。在本研究中,我们使用了新的单克隆抗体的锚定纤维,研究这一组成部分的BMZ。对11例基底细胞癌患者的皮肤肿瘤(10例结节性,1例浅表性)和1例基底细胞痣综合征患者的掌窝[10]进行了大疱性类天疱疮抗原(BPA)、层粘连蛋白和单克隆抗体AF 1和AF 2识别的锚定原纤维抗原的检查[4,5]。将一个楔形肿瘤(1-2 mm)冷冻在最佳切割温度(OCT)化合物(Lab-Tek Products,纳珀维尔,IL,美国)中,并储存在-70 ℃下直至测定。使用Tissue-Tek-II冷冻切片机切割4微米厚的切片,并置于明胶制备的载玻片上。在染色之前,将组织切片风干20分钟。
Basement-membrane-zone (BMZ) components are altered in basal-cell carcinoma (BCC). Electron microscopy has identified areas of normal, discontinuous, or absent BMZ components in human BCC [13, 15, 26]. In the present study, we used new monoclonal antibodies to the anchoring fibrils to study this component of the BMZ. Skin tumors of 11 patients with BCC (10 nodular, 1 superficial) and the palmar pit of a patient with basal-cell nevus syndrome were examined [10] for bullous-pemphigoid antigen (BPA), laminin, and anchoring-fibril antigens recognized by monoclonal antibodies AF1 and AF2 [4, 5]. A wedge of tumor (1-2 mm) was frozen in optimal cutting temperature (OCT) compound (Lab-Tek Products, Naperville, IL, USA) and stored at-70~ until assayed. Fourmicron-thick sections were cut using a Tissue-Tek-II cryomicrotome and placed on gelatin-prepared slides. The tissue sections were air-dried for 20 rain before staining.
