Circadian rhythm dynamics in human adult stem cells following synchronisation with dexamethasone. Quantitative RT-PCR analyses showing temporal expression profiles of clock genes collected every four hours between 16 h–52 h following synchronisation with dexamethasone. Data are expressed as the mean of ΔCt ± SEM relative to 16 h time point and normalised against the housekeeping gene GAPDH. Bars represent means ± SEM of 3 independent experiments.
