Research Abstract |
Urodeles have the ability to regenerate amputated limbs throughout their life span. In the present study, we attempted to elucidate how axolotls can specify limb type correctly during the regeneration process. We misexpressed Tbx5 in regenerating hindlimb blastema, and consequently a forelimb-like hindlimb regenerated from the hindlimb blastema. Therefore, we considered that Tbx5 plays a key role in the specification of forelimb during the regeneration process of axolotl limbs. However, we could not elucidate the factor in specifying forelimb blastema in the present study.
