Clock gene expression in synchronised human adult stem cells at two opposite circadian phases. Quantitative RT-PCR analyses showing the expression levels of clock genes after synchronisation with dexamethasone at two opposite circadian phases 12 h apart (20 h versus 32 h). Data are expressed as the mean of ΔCt ± SEM relative to the 20 h time point and normalised against the housekeeping gene GAPDH. Bars represent means ± SEM of 3 independent experiments, ^∗p < 0.05 (independent t-test).
