<p>All rBMSC aggregate groups had statistically significant increase in collagen over week 0. At week 3, 20 M HA also displayed the highest collagen/DNA. Collagen content for all the hWJC groups expressed as collagen/DNA (C&D) at week 0, 2, and 3. We noticed that the 20 M HA at week 0 had the highest collagen/DNA value. 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 particular group and (**) represents statistically significant difference from the control at that time point. (p < 0.05).</p
