A strain of breast tumor cell line ZHL2006 was established and biologically identified. The ZHL2006 cells grew fast in vitro and the population doubling time was 43.6h. Electronmicroscopical observation showed that there were microvilli on the surface of the cells, nucleus irregularity, karyoplasmic ratio increased, nucleolus distinctness, et al.. Chromosome number and structure were abnormal. Immunohistochemistry showed that PCK were expressed. The ZHL2006 cell line could form onto clone in soft agar and had oncogenicity in athymic mice.

ZHL2006细胞在体外生长迅速，群体倍增时间为43.6h；倒置相差显微镜及Giemsa染色镜下观察细胞为多边形及梭形；透射电镜观察可见细胞表面有微绒毛，核高度不规则，核浆比例增大，核仁明显等；染色体数目和结构异常；广谱细胞角蛋白染色阳性，说明其自上皮而非来自基质；同时ZHL2006细胞系在软琼脂中可形成克隆，具裸鼠致瘤性。

However, overall, a lobulated architecture is preserved.

所以，形态学特点是符合乳头部腺瘤伴有旺炽上皮增生和硬化性腺病改变的。

If you still think this is a intraductal papilloma after the IHC. Suggest that you read the book chapter of paillary lesion and the interpretation of myoepithelial markers again.

如果看过免疫组化之后，你仍然认为它是导管内乳头状瘤，建议你再次阅读乳头状病变和肌上皮标记物的有关章节。

Cytology revealed 3-dimensional groups of ductal cells in a background of myoepithelial cells and stromal cells, consistent with a fibroadenoma.

对该肿块进行细针抽吸活检，细胞学显示以肌上皮细胞和基质细胞为背景的三维导管细胞结构，与纤维腺瘤结构一致。

Objective: To establish a method of in vitro cultivation of epithelial cells of keratocystic odontogenic tumors.

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

We used the avidin-biotin complex technique and EGFR monoclonal antibody to evaluate the expression of EGFR in 29 cases of cholesteatoma and 34 samples of normal postauricular skin. Of patients with cholesteatoma, 79%(23 cases) had EGFR-positive cells in the basal layer, 66%(19 cases) in the parabasal layer, and 62%(18 cases) in the upper layer of the epithelial tissue.

本研究利用免疫组织化学酵素抗体法（avidin-biotin-peroxidase complex，ABC method）以 EGFR 单株抗体免疫染色，评估29例胆脂瘤与34例耳廓后皮肤两者组织上皮内 EGFR 阳性细胞之分布表现。

Angiomyolipoma of the kidney is a clonal neoplasm, apparently part of a family of neoplasms derived from perivascular epithelial cells.

肾脏平滑肌脂肪瘤是无性系肿瘤，部分有家族史，肿瘤来自血管上皮细胞。

Long believed to be a benign hamartoma, angiomyolipoma is now considered a neoplasm that arises from perivascular epithelioid cell.

长期以来被认为是一种良性的过误瘤，但最近几年来研究认为，这是一种起源自血管旁类上皮细胞的新生性肿瘤。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
