Effect of hTERT and GRP78 on the proliferation of rabbit chondrocytes. Growth curves of cultures of nontransfected control chondrocytes from young and old rabbits (YRA and ORA, respectively) and hTERT (YRA + hTERT and ORA + hTERT) and GRP78 (YRA + hTERT + GRP78 and ORA + hTERT + GRP78)-transfected chondrocytes. The mean number of cells is shown on a log10 scale.
