The Differential Effects of Leukocyte-Containing and Pure Platelet-Rich Plasma on Nucleus Pulposus-Derived Mesenchymal Stem Cells: Implications for the Clinical Treatment of Intervertebral Disc Degeneration

Figure 3

The proliferation of cells derived from nucleus pulposus in different concentrations of P-PRP or L-PRP. Cell proliferation was evaluated on day 7 by CCK-8 assay. The cell proliferation showed a maximum effect on 10% P-PRP and 10% L-PRP. Differences for the date from each group (P-PRP or L-PRP) performed by using one-way analysis of variance. A test was used for determining the statistical significant difference between P-PRP and L-PRP in each concentration of PRPs. Different letters above bars indicate that the difference is statistically significant ().
