Figure 6From: The matrix-forming phenotype of cultured human meniscus cells is enhanced after culture with fibroblast growth factor 2 and is further stimulated by hypoxiaSafranin-O staining of cell aggregates. Histological analysis and matrix accumulation of cell aggregates derived from meniscus cells expanded in the absence ((a) normoxia; (c) hypoxia) and presence ((b) normoxia; (d) hypoxia) of fibroblast growth factor 2 (FGF2). Scale bar, 100 μm. FGF2, fibroblast growth factor 2.Back to article page
