Chromosomes and nucleoli of the axolotl, Ambystoma mexicanum.
Amongst the axolotl's haploid complement of fourteen mitotic chromosomes, one of the four largest, with a greater arm asymmetry than the other three, shows a nucleolar constriction subterminally in its shorter arm. Low-temperature treatment causes further secondary constrictions to appear; these constrictions enable most of the mitotic chromosomes to be identified; the constrictions occur at si...

INTRODUCTION 14-19 follow one another rapidly while days The Mexican axolotl, Ambystoma may separate successive larval stages. mexicanum (also called Siredon The time between the stages is illusmericanum), has long been used in laboratrated in Fig. 1. The data for Fig. 1 were tories around the world. This convenient compiled by rearing embryos in a constantlaboratory animal probably will be use...
متن کاملExperiments on developing limb buds of the axolotl Ambystoma mexicanum.
Various experiments were performed on the limb buds of axolotls to compare the behaviour of amphibian limbs with that previously reported for chick limbs. Following removal of the tip or whole limb bud, extensive powers of regulation were observed since complete limbs always formed. Similarly after distal to proximal grafts intercalary regulation occurred to produce perfect limbs and after prox...
متن کاملRegeneration of Limb Joints in the Axolotl (Ambystoma mexicanum)
In spite of numerous investigations of regenerating salamander limbs, little attention has been paid to the details of how joints are reformed. An understanding of the process and mechanisms of joint regeneration in this model system for tetrapod limb regeneration would provide insights into developing novel therapies for inducing joint regeneration in humans. To this end, we have used the axol...
متن کاملMisexpression experiment of Tbx5 in axolotl (Ambystoma mexicanum) hindlimb blastema.
Axolotls (Ambystoma mexicanum) have the ability to regenerate amputated limbs throughout their life span. In the present study, we attempted to elucidate how axolotls can specify limb type correctly during the regeneration process. We misexpressed Tbx5 in regenerating hindlimb blastema, and consequently a forelimb-like hindlimb regenerated from the hindlimb blastema. On the other hand, no chang...
