Collagen types I and II, and SOX9 gene expression in human articular chondrocytes. (a) Collagen type I alpha 2 (COL1A2) gene expression levels of aggregate cultures of articular chondrocytes (n = 3) in 5% oxygen versus 20% oxygen. (b) Collagen type II alpha 1 (COL2A1) gene expression in aggregate cultures of articular chondrocytes (n = 3) in 5% oxygen versus 20% oxygen. (c) SOX9 (Sry-related HMG box-9) gene expression levels of cell aggregate cultures of articular chondrocytes (n = 3) in 5% oxygen versus 20% oxygen. Student's unpaired t-test. Data are expressed as mean ± standard deviation (n = 3).
