## Abstract We have reβexamined some of the factors affecting the induction of heartβforming mesodern in the axolotl. The formation of functional, rhythmically contracting myocardial tissue was used as an assay. We have found that heartβforming mesoderm is fully induced and capable of completing it

Abstract
Electrical recordings from the hearts of both cardiac lethal mutant and normal embryos showed the presence of action potentials conducted over the heart tube. Ionic coupling and gap junctions also were observed in both. These results suggest that the absence of heart function in mutant embryos does not result from a defect in electrical activity.

Expression of tropomyosin protein, an essential component of the thin filament, has been found to be drastically reduced in cardiac mutant hearts of the Mexican axolotl (Ambystoma mexicanum) with no formation of sarcomeric myofibrils. Therefore, this naturally occurring cardiac mutation is an approp
Recessive mutant gene c for "cardiac nonfunction" in axolotls results in an absence of normal heart contractions in affected embryos due to a failure of myofibril formation. In the present study, the intermediate filament protein, desmin, is compared in developing normal and mutant hearts by means o
Recessive mutant gene c in axolotls results in a failure of the heart to function because of abnormal embryonic induction processes. The myocardium in this mutant lacks organized sarcomeric myofibrils. The present study was undertaken to determine if developmental abnormalities were evident in other
When homozygous, recessive mutant gene c in Ambystoma mexicanum results in a failure of embryonic heart function. This failure is apparently due to abnormal inductive influences from the anterior endoderm resulting in an absence of normal sarcomeric myofibril formation. Biochemical and immunofluores
