In the gingiva of the mouse incisor, connective tissue cells were observed which were undergoing mitosis and contained collagen fibrils enclosed in vacuoles in their cytoplasm. The presence of intracellular collagen was noted in the majority of the dividing cells. On the basis of this observation it is suggested that renewal of the fibroblast population in the gingiva occurs preferentially by division of differentiated fibroblasts rather than by division of cells with a lower degree of differentiation.
在小鼠切牙的牙龈中，观察到结缔组织细胞正在进行有丝分裂，其细胞质中的液泡内含有胶原纤维。在大多数分裂细胞中都发现了细胞内胶原的存在。基于这一观察结果，有人提出牙龈中纤维母细胞群体的更新优先通过分化的纤维母细胞分裂，而不是通过低分化程度细胞的分裂来实现。
