Fig 5. Laser scanning confocal microscopy images (a and b) and quantification (c and d) of the relative levels of Dnmt1 in early embryos at the pronuclear and blastocyst stage, with or without Scriptaid treatment.

The numbers of embryos examined in each experimental group are shown in the bars. * indicates P<0.05 compared with the control group. Values are the mean (± standard deviation of the mean) of four independent experiments. Ctrl: no treatment; SCR: Scriptaid treatment. Magnification, × 400.
