Figure 3From: Human telomerase reverse transcriptase and glucose-regulated protein 78 increase the life span of articular chondrocytes and their repair potential Glycosaminoglycan content of chondrocyte cultures in atelocollagen honeycomb-shaped scaffolds with a membrane seal. The glycosaminoglycan (GAG) content of nontransfected (black bars) or hTERT- or GRP78-transfected (white bars) ORA chondrocytes on the indicated days. Results are expressed as the mean (SD) of 6 independent measurements. *P < 0.05.Back to article page
