# From Axolotl to Human: Scientists Discover Universal Regeneration Genes and Create First Therapy

The dream of a human body being able to regenerate lost tissues as effectively as some animals is getting closer to reality. Scientists have made a breakthrough in this direction by discovering universal genetic regeneration mechanisms and successfully testing the first experimental therapy.

Details of the study, published in the prestigious journal Proceedings of the National Academy of Sciences, describe how biologists managed to "hack" natural tissue repair codes by combining the efforts of three independent laboratories.

### Comparing Biological Superpowers

To find patterns, researchers compared three fundamentally different organisms, each possessing unique regeneration capabilities:

- **Mexican Axolotl:** This salamander is considered the absolute champion of regeneration. It can regrow limbs, tails with fragments of the spinal cord, and even restore parts of the heart, brain, lungs, and jaws.

- **Zebrafish (Danio rerio):** Possesses the ability to repeatedly and losslessly regenerate tail fins, retinas, spines, kidneys, and the pancreas.

- **Lab mice:** As the closest relatives to humans among mammals, they can fully regenerate fingertip tips if the nail bed remains intact.

Interestingly, a similar hidden ability exists in humans: under similar conditions, skin, bone, and soft tissues can regrow in human finger bundles.

### Discovery of the Key to Regeneration

Analyzing the protective layer (epidermis) of all three species during the healing process, a team led by Professor Josh Cury discovered a common pattern. Skin cells in the affected area begin to actively produce a group of so-called SP genes, including key factors SP6 and SP8.

To prove the decisive role of these genes, researchers applied CRISPR genetic editing technology. The results were unequivocal:

- When the SP8 gene was artificially removed from the axolotl genome, the salamander's amputated limbs lost the ability to form a proper bone structure.

- In mice deprived of both SP6 and SP8 factors, finger regeneration was completely blocked.

### First Successful Therapy

Based on this data, the plastic surgery laboratory of David Brown at Duke University developed a special cloud enhancer based on zebrafish genetic material. A viral gene therapy was created on its basis.

This therapeutic viral vector delivers the FGF8 molecule directly into tissues — a growth factor protein that is normally activated by the SP8 gene. The experimental results were astonishing: the therapy allowed partial restoration of bone tissue growth on damaged mouse fingers even in the complete absence of original regeneration genes.

### Prospects for Medicine

Although the adult human body currently lacks natural mechanisms for large-scale growth of lost organs, this study became the first successful proof of concept. It demonstrates that artificially created drugs can replace specific "regenerative epidermis" and force human cells to act according to the salamander scenario.

Scientists emphasize that years of clinical trials and additional testing lie ahead before the technology can be applied to human limbs. Nevertheless, the development of this innovative genetic method already creates a powerful foundation. In the future, it will complement and enhance other advanced medical fields, such as stem cell therapy and bioengineered scaffolds.
