- An islet cell adenoma is seen here, separated from the pancreas by a thin collagenous capsule. A few normal islets are seen in the pancreas at the right for comparison. 这是胰岛细胞腺瘤,通过一薄层的胶质囊与胰腺组织分离。与此处相对比,在右侧可见少数的正常的胰岛。
- However, hyperplastic basal cell in basal cell adenoma had not distinctive atypia.The border of hyperplastic nodal which had no pathological nuclear mitoses, invasion and necrosis was clear. 而基底细胞食品腺瘤内增生的基底细胞食品异型性不眼科明显,无病理性核分裂象,增生结节周界清,无浸润性边缘和坏死。
- However,the peak time of ETB mRNA receptor was at 6 hour and mainly localized on renal medullary tubule epithelial and collecting duct cells. ETB受体mRNA于再灌流6小时达高峰,主要分布髓质肾小管、集合管。
- Results Granular convoluted tubule (GCT) cells and striated duct cells showed SOM, SP, VIP, and NPY immunoreactivity while the acinar cells were negative. 结果大鼠颌下腺颗粒曲管和纹状管上皮细胞呈SOM、SP、VIP和NPY免疫反应性,而腺泡细胞为阴性。

- esinophilic cell adenoma of thyroid gland 甲状腺嗜酸性细胞腺瘤
- Paneth cell adenoma of the stomach 胃潘氏细胞腺瘤
- In pancreatic carcinoma most of APE/ref-1 expressed in nuclei and cytoplasm, and normal pancreas tissues, APE/ref-1 was positive in cytoplasm of pancreatic islet cells but negative in pancreatic duct cells and acini. 22例癌旁正常胰腺组织导管及腺泡阴性表达仅胰岛的细胞胞浆呈阳性表达。 可见APE/ref-1在胰腺癌多数定位于细胞的胞浆及胞核上,而在癌旁胰腺组织导管及腺泡呈阴性表达仅在胰岛胞浆呈阳性表达。
- An experimental study was carried out on the Mullerian duct cells, i.e. epithelial cells and stromal cells, treated with trypsin and isolated by Percoll gradient centrifugation. Then they were cultured separately. 本实验应用胰酶消化后的Percoll梯度分离技术,将苗勒管上皮细胞与间质细胞分离开来,然后分别进行细胞培养。
