El mecanismo que permite al pez cebra regenerar sus aletas hasta recuperar su tamaño original

Researchers have identified the biological mechanism that enables zebrafish to regenerate their caudal fins to their original size following an amputation. The process is directed by gradients of Erk activity, a cellular signaling pathway that functions as a biological gauge to determine the amount of tissue lost and guide the restoration of the appendage to its precise pre-injury dimensions. This discovery provides new insight into the complex cellular communication required for structural regeneration in vertebrates.
