Immunolocalisation of type I collagen in cell aggregates after 14 days of culture. 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). No primary antibody control and non-specific IgG control. Scale bar, 100 μm.
