One large cell with very large nuclei is seen near the center. 靠近中心处可见一很具有很大胞核的大肿瘤细胞。
TTF-1 PU was greater in squamous cell carcinoma cell nuclei than in large cell lung carcinoma cell nuclei ( P < 0.001). 肺鳞癌癌细胞核TTF-1的PU值大于肺大细胞癌癌细胞核TTF-1的PU值(P<0.001)。
Results The MSCs proliferated rapidly in in vitro culture and after a 2-to 3-week induction, the cells began to generate large amount of enlarged endoplasmic reticulum, Golgi complexes and mitochondria, with immature cell nuclei. 结果原代和传代培养的细胞具有活跃的增殖能力,诱导培养2~3周后,透射电镜下观察见大量扩张的粗面内质网、高尔基体和线粒体,细胞核较为幼稚。
Immunohistochemical staining were observed under confocal microscope after the cells were typical fibroblast morphology: large cell body, many processes of the spindle or star of flat cells, oval nuclei were regular, multi-nucleoli. 免疫组织学染色后共聚焦显微镜观察可见细胞为典型的成纤维细胞形态:大胞体,多突起的纺锤形或星形的扁平细胞,细胞核呈规则的卵圆形,多核仁。
