Mouse brains expressed reporter genes which had been introduced by in vivo electroporation: upper panels, E15.5 telencephalons expressing EYFP, 2days after electroporation at E13.5; lower panels, P15 telencephalons expressing DsRed (left) and EYFP (right), after electroporation at E13.5 (left) and E16.5 (right). Scale bars, 200 µm.
