Regeneration x sex position

Description:This regenerative failure emerged after sexual maturity, was mimicked in androgen-treated females, and was suppressed in males by androgen receptor antagonism. Summary Teleost fish and urodele amphibians regenerate entire fins and limbs after amputation, while such potential is absent in avians and limited in mammals to digit tips [ 1 , 2 ]. These animals have an apparently limitless regenerative capacity, and the asexual animals seem to maintain their telomerase levels throughout their lifetime, making them "effectively immortal". Thus, one of their gametes will combine with the gamete of another planarian. As a model system in biological and biomedical research[ edit ] The life history of planarians make them a model system for investigating a number of biological processes, many of which may have implications for human health and disease.
