Figure 2From: Prostaglandin E2 regulates the expression of connective tissue growth factor (CTGF/CCN2) in human osteoarthritic chondrocytes via the EP4 receptorQuantitative PCR for CTGF expression in chondrocytes: different time points. Chondrocyte samples (n = 3, a different panel from Figure 1) were stimulated with PGE2 (10 nM) for 4 or 24 h, and each sample was analysed for the CTGF mRNA as in Fig. 1.Back to article page
