Identification and Clonal Characterisation of a Progenitor Cell Sub-Population in Normal Human Articular Cartilage

Abstract

In conclusion, we propose that we have identified and characterised a novel cartilage progenitor population resident in human articular cartilage which will greatly benefit future cell-based cartilage repair therapies due to its ability to maintain chondrogenicity upon extensive expansion unlike full-depth chondrocytes that lose this ability at only seven population doublings.
