Figure 4.

The level of mRNA expression of the Sox9 gene that was transduced with recombinant adenovirus vector in the nucleus pulposus is shown. Lines 1, 3, and 5 represent the mRNA expression of the Sox9 gene that was transduced with adenovirus in group D at 1, 4, and 8 weeks, respectively. PCR results showed that there was no mRNA expression during the treatment period; lines 2, 4, and 6 represent the mRNA expression of the Sox9 gene that was transduced with AdSox9. PCR results showed that there was a gradual increase in the expression of Sox9 in group C with time
