Frequently Asked Questions
Animals like salamanders possess unique biological mechanisms such as a high number of stem cells, the capacity to form a blastema (a mass of tissue capable of growth and regeneration), and specific genetic factors that enable limb regrowth, which humans lack.
Significant advances include stem cell therapy, tissue engineering, and bioengineering approaches that aim to mimic natural regeneration processes, with ongoing research focused on overcoming human biological limitations to make limb regeneration a possibility.
