Cell viability. The effects of LD alone or with 10% PRP on cell viability were assayed in chondrocytes maintained for 24 h in medium (starved-cells), in medium containing 10% FBS (FBS-cell) or 10% PRP (PRP-cells). Date are expressed as mean ± SD. The experiments were repeated thrice, in triplicates. *P < 0.005 vs cell untreated of each experimental group (PBS)
