摘要

采用间接免疫荧光显微镜,用特异性抗角蛋白抗体研究了蟾蜍和青蛙膀胱中中间纤维的分布。我们的研究结果表明,在这两个物种中,内衬膀胱的上皮细胞都富含细胞角蛋白,并以丝状网络的形式组织起来。颗粒细胞是面向尿腔的最丰富的细胞,抗利尿激素促进位于尿腔细胞质中的膜管结构与顶细胞膜的融合。中间纤维在抗利尿激素诱导的细胞膜重排中的作用被提出。

Distribution of intermediate filaments in epithelial cells of the amphibian urinary bladder: an immunofluorescence study.

The distribution of intermediate filaments in toad and frog urinary bladder was studied on frozen sections by indirect immunofluorescence microscopy using specific antiprekeratin antibodies. Our results show that in both species, epithelial cells lining the urinary bladder are very rich in cytokeratin, organized as a filamentous network. In granular cells, the most abundant cells facing the urinary lumen, vasopressin promotes fusion of the membranous tubular structures located in the luminal cytoplasm with the apical cell membrane. A role for intermediate filaments in the membrane rearragements induced by vasopressin in these cells, is proposed.
