Figure Lengend Snippet: Experimental setup and essential equipment for in utero electroporation (A) Image of the whole setup for in utero electroporation. (B) Images of the electroporator to deliver electrical stimulation to pups (upper) and the micro injector to inject the plasmids (lower). (C) Images of surgical implements and a glass pipette which contains the diluted solution including plasmids for in utero electroporation. (D) Scheme of the in utero electroporation. The plasmid is injected into the fetal lateral ventricle and electrical stimulation is delivered via the forceps-shaped bipolar electrode. The electroporation is performed on 6–8 embryos in a single operation. (E) Inject the solution containing the plasmid into one side of the lateral ventricles on each embryo. The injection site of the plasmid should be 0.75–1.0 mm anterior from lambda and 0.5 mm lateral from the sagittal suture. (F) The positions of the electrode to target the mPFC. Note that the negative pole is positioned over the injected hemisphere while the positive one is positioned on the contralateral side. The two electrodes are slightly angled rostrocaudally and vertically as seen. (G–I) Low (G) and high (H) magnification Images of injection of the plasmids and image of delivering electrical stimulation through a forceps-shape electrode (I) during in utero electroporation. (J) Image of the mPFC from an electroporated mouse. The green signal shows GFP and the blue signal represents DAPI staining. Scale, 1mm. (K) High-magnification image of the electroporated mPFC expressing GFP. Scale, 50 μm. See also .
