In 25 human intervertebral discs studied by electron microscopy, sheathing collagen-like fibrils by electron-dense cylinders was observed. The sheaths consisted of layers of dense granules 3 to 12 times the diameter of the enclosed collagen-like fibrils, and they appeared to be more frequent in older discs.
在通过电子显微镜研究的25个人类椎间盘样本中,观察到了由电子致密圆柱体包裹的类胶原纤维。这些鞘由多层致密颗粒组成,其直径是所包裹类胶原纤维直径的3至12倍,并且在较老的椎间盘中似乎更为常见。
