Replicative aging of human articular chondrocytes during ex vivo expansion
1 Nov 2002
Abstract excerpt
OBJECTIVE: To investigate the contribution of clinical ex vivo expansion protocols to replicative aging of human chondrocytes. METHODS: Primary human chondrocytes were cultured as monolayers after isolation from 7 articular cartilage specimens. Cells were passaged corresponding to 12-19 cell population doublings (cpd). Aliquots of the cells were collected from each passage and analyzed for telomere length and...
