OCN Gene ExpressionO N D J F M A MMonth of Serum CollectionFigure 6.51—Longitudinal analysis of OCN gene expression in cells differentiated for 6 daysin seasonal bear serumMC3T3-E1 cells were differentiated in seasonal bear serum for 6 days, followed by real-timePCR quantification of relative gene expression. Each point represents the gene expressionresponse from one serum sample. Vertical lines represent transitions between active andhibernating seasons. Samples are from 2 black bears in the 2006/07 season.OPG Gene ExpressionO N D J F M A MMonth of Serum CollectionFigure 6.52—Longitudinal analysis of OPG gene expression in cells differentiated for 6 daysin seasonal bear serumMC3T3-E1 cells were differentiated in seasonal bear serum for 6 days, followed by real-timePCR quantification of relative gene expression.
