Abstract

In recent years it has become increasingly clear that articular cartilage harbours a viable pool ofprogenitor cells and interest has focussed on their role during development and disease. Analysis ofprogenitor numbers using fluorescence-activated sorting techniques has resulted in wide-rangingestima...
