Figure 5From: Identification of subpopulations with characteristics of mesenchymal progenitor cells from human osteoarthritic cartilage using triple staining for cell surface markersChondrogenesis and adipogenesis of culture expanded and progenitor marker sorted osteoarthritic cartilage derived cells. Culture expanded cells were stained as follows: (a) Alzian blue, (c) collagen type II, (e) cartilage oligomeric matrix protein (COMP) and (g) oil-red. The marker sorted cells are shown in (b) Alzian blue, (d) collagen type II, (f) COMP and (h) oil-red.Back to article page
