Hyaluronic Acid (800 kDa) Supplementation of University of Wisconsin Solution Improves Viability of Osteochondral Grafts and Reduces Matrix Metalloproteinase Expression during Cold Preservation

Figure 4

Real-time PCR analysis of OCTs cold preserved in the presence and absence of hyaluronic acid. Expression of MMP-2 (a), MMP-3 (b), MMP-9 (c), and MMP-13 mRNAs (d) in OCT stored for two weeks in UW solution (UW) and UW solution supplemented with 800 kDa HA (HA800). a statistically significant difference between the UW and UW with HA800 groups. All data are shown as the mean ± SE ().
