Gene expression of Collagen I, Aggrecan, SOX9, and Runx-2 for hWJC groups at week 0, 2, and 3.

<p>hWJC groups at week 0, 2, and 3. There was a significant difference in SOX9 and Aggrecan gene expression at week 3 by groups 20 M HA and 20M HA CS groups. Values are reported as mean ± standard deviation, n = 4. (*) represents statistically significant difference over the week 0 value. (#) represents statistically significant highest value of the group (**) represents statistically significant difference from the control at that time point. (p < 0.05).
