At high magnification , this poorly differentiated prostatic adenocarcinoma demonstrates cells with nucleoli and mitotic figures 高倍镜下低分化的前列腺癌的细胞中可见核仁和核分裂像。
Tight packaging of small acini creates a near - solid appearance . there is no cytologic atypia . mitotic figures are rare 瘤细胞排列紧密,近似于实性外观。没有非典型增生,有丝分裂相罕见。
Quiescent center a group of cells in the center of the apical meristem in which mitotic divisions are rate or absent 静止中心:在根的顶端分生组织中心区域的一些细胞,它们几乎不进行有丝分裂。
Alternatively , like allopolyploids , they may arise by the nondisjunction of chromatids during the mitotic division of a zygote 与异源多倍体相似的是,它们也是在有丝分裂中合子的染色单体不分离形成的。
At high magnification , the non - hodgkin ' s lymphoma cells have prominent clumped chromatin and nucleoli with occasional mitotic figures 高倍镜非霍奇金淋巴瘤细胞有明显的染色质浓缩,偶尔可见处于核分裂。
Thus , it is evident that 3t3 - l1 preadipocytes could differentiate into adipocytes without dna synthesis and mitotic clonal expansion 这些结果说明克隆扩增和dna复制并不是3t3 l1前脂肪细胞分化的必需步骤。
Two cases of renal leiomyosarcoma were reported : the first case showed a well - encapsulated tumor with low mitotic rate 摘要本文报告两个肾脏平滑肌肉瘤的案例:第一个案例为一具有完整包膜的肿瘤,且为低细胞分裂率。
There is no cytologic atypia in this case . rare cases may show mild cytologic atypia . increased mitotic is usually not seen 本例未见到细胞异型性。极少的病例中可显示轻度的细胞异型性。增加的有丝分裂像通常见不到。
Elongation the enlargement of cells after mitotic division that results from the uptake of water by osmosis until the cells become turgid 延伸,延长:有丝分裂后的细胞,通过渗透作用摄取水分使细胞体积变大,变得比较饱满的现象。
However , about 25 % of cases exhibit frank malignant features of prominent nuclear pleomorphism ( as in this case ) , mitotic activity or necrosis 然而,大约25 %的病例显示恶性特征诸如明显核多型现象(比如此例) 、核分裂活性或者坏死。
