The existence of multipotent cells in the adult tissues and organs of those vertebrates that
are capable of regeneration has been accepted for decades. Although studies of vertebrate …

The axolotl is one of the few tetrapods that are capable of regenerating complicated
biological structures, such as complete limbs, throughout adulthood. Upon injury the axolotl …

We have described a formal model for pattern regulation in epimorphic fields in which
positional information is specified in terms of polar coordinates in two dimensions. We …

Distal Regeneration and Symmetry Page 1 they have the same mass and lifetime?" Now with
parity violation both are recognized as K mesons, K1,2 and K1,38. L. W. Alvarez, FS Crawford …

Retinoic acid (RA), a derivative of vitamin A, has remarkable effects on developing and
regenerating limbs. These effects include teratogenesis, arising from RA's ability to inhibit …

The amphibian limb is a model that has provided numerous insights into the principles and
mechanisms of tissue and organ regeneration. While later stages of limb regeneration share …

Some aspects of the influence of position on regeneration have been examined by
comparing regeneration from two different levels along the newt forelimb. 2. We have …

Dlx-3, a homolog of Drosophila Dll, has been isolated from an axolotl blastema cDNA
library, and its expression in developing and regenerating limbs characterized. The normal …

Homeobox genes are important in the regulation of outgrowth and pattern formation during
limb development. It is likely that homeobox genes play an equally important role during …

Using the triploid/diploid cell marker in the axolotl, Ambystoma mexicanum, we have
analyzed the extent to which cells derived from the dermis and the skeleton contribute to the …
