Figure 1. — The expression of miR-21 in human nucleus pulposus tissues. (A) The expression of miR-21 in four degenerative nucleus pulposus tissues and four idiopathic scoliosis nucleus pulposus tissues. These degenerative NP tissues exhibited significantly higher expression of miR-21 compared to the control; (B and C) TaqMan RT-PCR analysis of miR-21 in nucleus pulposus tissue from other 50 patients; (D) The correlation between the expression of miR-21 and the disc degeneration grade of the patients. The error bars represent SD. ** indicates p < 0.01.
