【摘要】 目的 应用CLSM对肝细胞癌标本的石蜡切片进行三维重建,显示立体形态特点,探讨CLSM在肿瘤病理学中的应用.方法 30μm石蜡切片,YOYO-1碘化物DNA荧光探针标记细胞核,CLSM连续光学切片、三维重建,观察肝细胞癌、不典型增生及正常肝组织的三维形态特点.结果 肝癌细胞核排列紊乱、积堆,体积增大、大小不等、明显多形;核表面不规则、凹凸不平、荧光强度不均;核内染色质分布不均、结构粗糙、多浓集于核膜下.结论 CLSM的断层扫描和三维重建功能提供了高精密度的三维图象和丰富信息,有助于准确诊断.更多还原

【Abstract】 PURPOSE To investigate the application of CLSM in tumor pathology with the three dimensional reconstruction by confocal laser scanning microscopy in routine pathologic specimens of HCC, METHODS 30 μm thick sections were cut from the paraffin-embedded tissues of HCC. hyperplasia and normal liver, stained with the DNA fluorescent probe YOYO-1 iodide and examined by CLSM to collect optical sections and 3D reconstructed images. RESULTS HCC displayed chaotic arrangement of carcinoma cell nuclei, marked pleomorphism. indented and irregular nuclear surface, and irregular and coarse chromatin texture. CONCLUSION The serial optical tomograms of CLSM can be used to create 3D reconstruction of cancer cells. Such 3D impressions might be helpful or even essential in arriving at an exact diagnosis更多还原
