[In Ovo] Misexpression of the gene of interest by in ovo electroporation


Injection plasmid solution colored by Fast Green into the central canal

Illustration of electrodes on the vitelline membrane - overlying embryos

(1) Injection of the plasmid solution colored by Fast Green into the central canal

(2) A pair of electrodes are put on the vitelline membrane overlying the embryos, and a 25V, 50 ms rectangular pulse was charged 4 times.

(3) We can monitor the transfection efficiency by electroporating GFP expression vector.


Monitoring transfection efficiency with the GFP expression vector


(4) Strong GFP fluorescence could be detected even 48 hours after electroporation.

(5) Right side of the embryo is transfected, hence the left side could be served as the controll (Dorsal view)



Mechanisms of brain regionalization and neural circuit formation have been studied by misexpression of transcription factors (En1/2, Pax2/5/6, Otx2, Gbx2), secreted factors (Fgf, Shh, semaphoring), signal transduction molecule (Ras, Sprouty2) and receptors (neuropilin)
