The oviduct epithelium of the Japanese quail is a monolayered epithelium consisting of two types of columnar cells, goblet type gland (G-) cells and ciliated (C-) cells. We found these cells to be arranged in a checkerboard pattern. Three types of cell boundaries formed between the two different types of cells were examined statistically at various levels of the columnar cells. There was a tendency on the part of the cells to form boundaries between G- and C- cells rather than between two C- cells or between two G- cells. We therefore propose that the pattern is constructed under a rule of maximizing the length of boundaries of two different types of cells owing to the fact that theirs is the greatest adhesion capacity. The role of microfilament bundles running along the apical cell boundaries is also discussed. It is suggested that they are in a tense state so as to shorten total length by contraction.
日本鹌鹑的输卵管上皮是一种单层上皮，由两种柱状细胞组成，即杯状腺（G-）细胞和纤毛（C-）细胞。我们发现这些细胞呈棋盘状排列。在柱状细胞的不同水平上，对两种不同类型细胞之间形成的三种细胞边界进行了统计学检查。细胞倾向于在G-细胞和C-细胞之间形成边界，而不是在两个C-细胞之间或两个G-细胞之间形成边界。因此，我们提出，由于两种不同类型细胞之间的粘附能力最强，这种模式是在使两种不同类型细胞边界长度最大化的规则下构建的。还讨论了沿细胞顶端边界延伸的微丝束的作用。有人认为它们处于紧张状态，以便通过收缩缩短总长度。
