Mechanical stress caused gradual IDD and LBP in NPCs. (a, b) NPCs exhibited gradual downregulated expression of ECM-related gene of aggrecan and upregulated expression of IDD-related gene of MMP3, with a time-response manner. (c, d) NPCs had significantly upregulation of LBP-related gene of CGRP and substance P, with a time-response manner. (The data are shown as . , , and when compared among each group. One-way ANOVA and Tukey’s HSD multiple comparison test were used for statistical analysis).
