What is Pigment Cell Development After Exchange of Neural Folds Between the California Newt and the Mexican Axolotl about?

Trunk neural folds from both black and white axolotls, Ambystoma mexicanurn, were transplanted unilaterally in place of folds of Taricha torosa neurulae. Melanophores from either kind of axolotl completely suppress the differentiation of T. torosa melanophores for several stages and largely suppress it for much longer. During larval stages host pigmentation gradually develops, but axolotl pigmentation always dominates. After metamorphosis the typical Ambystoma spotted pattern appears. During all stages donor melanophores are almost equally distributed on both flanks, with only slightly more on the grafted side. Guanophores predominate on the grafted side, while xanthophores predominate on the opposite side. With the exception of the distribution of axolotl melanophores, these results confirm results of others with the black axolotl and offer additional evidence that the chromatophores of both black and white axolotls are equivalent. New suggestions are made to explain the unequal distribution of xanthophores and guanophores in view of the nearly equal distribution of axolotl melanophores. Trunk neural folds of T. torosa were transplanted bilaterally in place of white axolotl neural
