Before revision:  The mean square displacement, \Delta(t), of cells exhibits glassy behavior at times comparable to the cell cycle time, while exhibiting super-diffusive behavior, \Delta (t) \approx t^{\alpha}  , at longer times.
After revision:  The mean square displacement, \Delta(t), of cells exhibits glassy behavior at times comparable to the cell cycle time, while exhibiting super-diffusive behavior, \Delta (t) \approx t^{\alpha} (\alpha > 1) , at longer times.
