Summary

We have performed the following experiments on the regenerating forelimbs of the newt Triturus cristatus: 1) Limb bud blastemata were ipsilaterally rotated at angles 90° or 270°. 2) Blastemata were contralaterally transplanted so that their anteroposterior axis coincided with the dorsoventral or ventrodorsal axis of the stump. The morphology and histological structure of the emerging supernumerary limbs for both experimental setups were examined. Different models for regeneration provide diverging predictions for the above experiments. Our results are in agreement with an extended version of the Polar Coordinate Model.
