Effect of epigallocatechin-3-o-gallate and quercetin on the cryopreservation of cartilage tissue.

The effects of epigallocatechin-3-o-gallate (EGCG) and quercetin on the contents of extracellular matrix (ECM) in porcine cartilage at 4 °C were investigated. The addition of quercetin at 0.01 mM for the incubation of porcine cartilage disks at 4 °C for 2 week could suppress the decrease in ECM and the compliance of the disks, markedly greater than those of EGCG (1.0 mM).
