Electroporation method into axolotl DRGs was established.
Fgf8-AcGFP and Bmp7-AcGFP were electroporated into axolotl DRGs.
Distribution of Fgf8/Bmp7-AcGFP was investigated in regenerating blastemas.
Knockdown of Fgf8 and Bmp7 by dsRNA interference impaired blastema induction.
Fgf8 and Bmp7 derived from DRGs are essential for blastema induction.
