Intercalary Regeneration in Larval Ambystoma Limbs: The Origin of Skeletal Structures and The Non-Segmental Organization of Morphogenetic Information
Abstract
dc:descriptionUrodele limbs are able to regulate for intercalary deletions created when distal regeneration blastemas are grafted to a more proximal level. Using several morphological markers, pigmentation differences between white and dark axolotls, and the difference in nucleolar number between diploid and triploid animals, I show that the entire intercalary regenerate is derived from the stump when wrist or tarsus blastemas are grafted to the mid-stylopodium of the fore- or hindlimb. The transplanted prospective autopodium forms no more than would be expected in situ. Thus, the rule of distal transformation is not violated during intercalary regeneration in salamanders.
