Abstract:
Objective To explore the method and technique to gain adequate seed cells for cartilage tissue engineering Methods hTERT gene was introduced into rabbit mandibular condylar chondrocytes by eukaryotic vector Rapidly proliferated immortalized chondrocytes in positive clones in micro carrier rotary cell culture system (RCCS) were screened and selected The growth of immortalized chondrocytes and the metabolic rate were observed Collagen type Ⅱ expression of immortalized chondrocytes of the experimental groups was observed The immunohistochemical results were compared with those of the control groups Results The immortalized chondrocytes in experimental groups could grow rapidly with a high metabolic rate and shorter population doubling time (PD) ( P
