What notable regenerative capacity allows zebrafish to perfectly regrow which body part mentioned in the text?
Answer
A fin
Zebrafish possess remarkable regenerative capabilities that are of intense interest to biomedical researchers because humans lack this ability for complex structures. If a zebrafish loses a fin, it is capable of regrowing that structure perfectly, meaning it restores the complete complexity of the original appendage. This regenerative power extends beyond fins; they can also repair damage to important internal organs such as the heart, the pancreas, and even sections of the brain. Studying the pathways utilized by the zebrafish to heal these tissues is a major goal in the hope of developing human treatments for injuries or degenerative diseases.
