Conclusions: Besides aging, weight bearing is probably a key factor of the increase of anulus fibrosus cells apoptosis and the degeneration of annulus fibrosus of intervertebral disc.

结论：除增龄外，负重是增加纤维环细胞凋亡、加重椎间盘纤维环破损和退变的重要因素。

Conclusions Anulus fibrosus cells isolated from nondegenerative intervertebral discs can differentiate into adipocytes, osteoblasts, chondrocytes, neurons, and endothelial cells in vitro.

结论：从未退变的椎间盘分离的纤维环细胞能在体外分化为脂肪细胞、格根包尔氏细胞、软骨细胞、神经元及内皮细胞。
