Gene transfer into embryonic brains using in utero electroporation technique

1) Materials

2) In Utero Electroporation Procedure

Electroporation settings for ICR mice

Age	Electrode (diameter)	Voltage	Pulse On	Pulse Off	Number of Pulses
E12.5	3mm	33V	30msec	970ms	4
E13.5	5mm	30V	50msec	950ms	4
E14.5	5mm	33V	50msec	950ms	4
E15-	5mm	35V	50msec	950ms	4

If viability was prioritized over transfection efficiency, the number of pulses can be changed to two.

The actual current is displayed on the screen of the electroporator (NEPA21/CUY21/CUY21E, Nepa Gene). Make sure that the current would become 30-60mA. The current varies according to how the electrode applied or wetness of the uterine horn. Examine the gap between electrodes and the electrode contact areas to fit the current in the appropriate range. If the current is still above the range after the examination, change the voltage setting.

3) GFP expression

CAG-EGFP was injected into the both lateral ventricles of E14.5 mouse embryos and electronic pulses (33V, 50msec) were charged four times. 3 days later, the embryos (E17.5) were fixed and the brains were removed and examined under a fluorescence stereomicroscope (Fig. A).
Fluorescence was observed in the lateral region of the hemisphere onto which the anode had been placed and in the medial region of the opposite hemisphere.

Brains were frozen and sliced and the fluorescent image was obtained with a confocal laser microscope (Fig. B). GFP positive cells into which DNA was transferred at the ventricular zone (VZ) migrated to the intermediate zone (IZ) and cortical plate (CP). The arrowheads show the border between VZ and IZ and the border between IZ and CP. Dashed line show the border of tissues.
VZ: Ventricular Zone, IZ: Intermediate Zone, CP: Cortical Plate
