Solitary cilia occur in motile as well as in non-motile fibroblasts of the peridontal ligament. The cells which moved with the erupting incisor are bipolar and oriented with their long axes parallel to the tooth surface. In cross section these cells have a flattened appearance. Cilia are localized in close vicinity to the nuclear area and show a definite orientation with respect to the transverse cell axis. The frequency of occurrence of this organelle was estimated from the percentage of diplosomes containing a basal body. Analysis of the composition of the paired structures indicated that at least 70 per cent of the fibroblasts are ciliated. The frequency of cilia in motile fibroblasts does not differ from that in non-motile cells suggesting that the presence of this organelle is not directly associated with cell locomotion.
孤立纤毛存在于牙周膜的运动性和成纤维细胞中。随着切牙萌出而移动的细胞是双极的，其长轴与牙齿表面平行。在横切面上，这些细胞呈扁平状。纤毛位于靠近核区的位置，并相对于细胞横轴呈现出明确的方向。通过含有基体的双联体的百分比来估计这种细胞器的出现频率。对成对结构组成的分析表明，至少70%的成纤维细胞有纤毛。运动性成纤维细胞中的纤毛频率与非运动性细胞中的纤毛频率没有差异，这表明这种细胞器的存在与细胞运动没有直接关联。
