Figure 4From: Human telomerase reverse transcriptase and glucose-regulated protein 78 increase the life span of articular chondrocytes and their repair potential mRNA expression levels of type II collagen in transfected chondrocytes. The mRNA expression of type II collagen was observed in ORA, regardless of different gene transfection. Profiles of control, GRP78 +, hTERT +, and hTERT +/GRP78 + cells were prepared to investigate expression of type II collagen. The mRNA expressions of GRP78 +, hTERT +, and hTERT +/GRP78 + cells were significantly higher than that in control of non-transfective ORA. GAPDH was used as an internal control to normalize RNA levels.Back to article page
