Figure 5From: Human telomerase reverse transcriptase and glucose-regulated protein 78 increase the life span of articular chondrocytes and their repair potential Macroscopic and immunostaining of regenerated cartilage after implantation. Postoperative appearance of repaired osteochondral defects in old rabbits implanted with scaffolds seeded with either nontransfected (top panels) or hTERT- and GRP78-transfected ORA chondrocytes (bottom panels) either 8 (A, D) or 16 (B, E) weeks after surgery. Immunostaining of type II collagen in tissue sections from rabbits implanted with scaffolds seeded with nontransfected (C) or hTERT- and GRP78-transfected (F) ORA chondrocytes. Each micrograph is representative of 8 tissue samples. Scale bar = 1.0 mm.Back to article page
