The cells of the upper strata of mammalian epidermis are flattened and aligned to form regular columnar units. It has been suggested that the position of the smaller underlying basal cells is related to the overlying cell columns. Examination of the position of metaphase figures in sheets of mouse epidermis indicated that mitosis occurs principally in cells lying just within the periphery of the cell columns but that there is no alignment of interphase basal cells within the columnar peripheries which could account for this position of mitosis.
哺乳动物表皮上层的细胞扁平且排列整齐，形成规则的柱状单元。有人提出，下方较小的基底细胞的位置与上方的细胞柱有关。对小鼠表皮片中期图像位置的检查表明，有丝分裂主要发生在刚好位于细胞柱周边内的细胞中，但在柱状周边内的间期基底细胞没有排列方式可以解释这种有丝分裂的位置。
