Why can’t we grow back amputated organs like zebrafish?

HYDERABAD:  Why do human beings not have the same capacity of regeneration as in zebrafish?

In some animals like zebrafish (a vertebrate), star fish and ascidian (primitive marine animal), limbs or other organs get regenerated when amputated. Zebrafish regenerates a wide variety of tissues, including heart, fin, spinal cord and optic nerve and the regenerative process is much faster. For instance, if a fin in zebrafish is amputated, it grows back within a fortnight, while it is not so in the case of human beings.

With zebrafish being 70 per cent similar to humans at genomic level, scientists from the Centre for Cellular and Molecular Biology (CCMB) are studying the bio-mechanism of regenerative process in that animal at the molecular level. They are also looking at star fish and ascidian, although non-vertebrates, to gain more insight into the role of proteins in the regeneration of tissue…..
