Figure 2From: Identification of subpopulations with characteristics of mesenchymal progenitor cells from human osteoarthritic cartilage using triple staining for cell surface markersFlow cytometric analysis of combinations of progenitor markers on freshly isolated and culture expanded chondrocytes from osteoarthritic cartilage. The label 'native' represents the fluorescence-activated cell sorting analysis after tissue digestion, whereas 'cultivated' indicates the analysis after culture expansion. The number of patients used for every analysis is indicated above every box plot. The dot presents the arithmetic mean of all the data in the category.Back to article page
