Multiple regeneration from axolotl limb stumps bearing cross-transplanted minced muscle regenerates : brief note

Abstract

Flexor and extensor muscles in the upper arms of axolotls were minced and cross-transplanted. The limbs were amputated 5 and 30 days after mincing. In each experiment a high percentage of the regenerates consisted of multiple limbs. This demonstrates that the morphogenetic information which produces multiple regenerates after the cross-transplantation of limb stump muscle is stable enough to be expressed after both mincing and the subsequent tissue regeneration of the muscle.
