CORE--Pathology

Core E将提供所有组织学、组织化学、电子显微镜和免疫组织化学技术 四个项目所要求的。此外，核心E将提供组织病理学解释和量化 根据项目要求对组织和培养细胞进行图像分析。两名病理学家和一名 组织技术员由核心人员组成。这两位病理学家与项目负责人密切合作， 确保实验结果的质量。核心操作5个配备有荧光的显微镜 以及亮场显微镜和数字成像，供核心人员和研究人员使用 项目。核心还保留了两个共焦显微镜，用于详细的荧光研究。《剧目》 染色包括H&E、三色、亚甲胺银和苦味酸天狼星红。最常受雇的人 免疫染色适用于Kit和Ki-67。此外，核心提供了广泛的免疫组织化学 使用不同抗体的程序。TUNEL检测假定的凋亡细胞是核心的常规方法。 图像定量分析程序包括细胞频率、胶原蛋白的直接实测法 大体、光学显微镜和电子显微镜的体积密度测量的点计数 图像。

Core E will provide all histological, histochemical, electron microscopic and immunohistochemical techniques required by the four projects. In addition core E will provide histopathological interpretations and quantitative image analyses on tissues and cultured cells as required by the projects. Two pathologists and a histotechnician comprise the core personnel. The two pathologists work closely with the project directors to assure the quality of the experimental results. The core operates 5 microscopes equipped for fluorescence and bright field microscopy and digital imaging for use of the core personnel and researchers from the projects. The core also maintains two confocal microscopes for detailed fluorescence studies. The repertory of stains includes H&E, trichrome, methenamine silver and picric acid Sirius red. The most often employed immunostains are for Kit and Ki-67. In addition the core provides a wide range of immunohistochemical procedures using diverse antibodies. TUNEL assays for presumptive apoptotic cells are routine in the core. Quantitative image analytic procedures include cell frequency, collagen assay by direct a real measurement and point counting for volume density measurements on gross, light microscopic and electron microscopic images.
