In metamorphosed individuals, however, the ability to regenerate is greatly diminished. In each experimental condition, 15 larvae on stage 44 immediately after hatching were maintained during 21 days and development and growth were weekly recorded. It is not certain that Ambystoma velasci specimens were not included in the original shipment.

They can also readily accept transplants from other individuals, including eyes and parts of the brain—restoring these alien organs to full functionality.

According to the results obtained in the present work, we conclude that among the solutions used for the culture of the axolotl Ambystoma mexicanum in Mexico, the Holtfreter’s medium guarantees a suitable development and growth of the organisms. Since the embryos survive xjolote to hatching with no heart function, the defect is very observable.
