Sharjah 24 – WAM: A recent scientific study suggests that the Mexican axolotl, an amphibian known for its distinctive appearance and remarkable regenerative abilities, could help pave the way for future treatments enabling human limb regrowth after amputation.

Axolotl’s unique regenerative ability

The endangered Mexican axolotl is widely used in research because it can regenerate entire limbs as well as parts of vital organs, making it a powerful model for studying tissue repair.

Shared genetic mechanisms identified

Published in the Proceedings of the National Academy of Sciences, the study compared axolotls with zebrafish and mice, identifying shared genetic pathways involved in regeneration. Researchers highlighted the role of SP genes, which activate tissue and bone growth processes.

Early progress in experimental therapy

Scientists also succeeded in stimulating bone growth in mice using experimental gene therapy, offering early evidence that similar mechanisms could one day be applied to humans.

Promising but early-stage findings

While still in the experimental stage, the research represents a significant step toward potential future therapies that could enable regeneration of damaged or lost human tissues and limbs.
