ON THE IMMORTAL HYDRA. AGAIN
https://doi.org/10.1234/XXXX-XXXX-2014-4-15-19
Abstract
The long history of ideas about the most famous “immortal” (non-aging) organism, freshwater hydra, is shortly reviewed. Over the years this polyp has attracted the attention of naturalists interested in problems of aging and longevity. In recent years this interest is abruptly increased with the accent on fine mechanisms providing almost complete lack of aging in hydra. It is emphasized that hydra immortality is based on indefinite self-renewal capacity of its stem cells. It is this fact allows polyp to continuously replace “outworn” cells of the organism keeping all its characteristics unchanged for almost unlimited time. It is concluded that the applicability of the data obtained in gerontological experiments on hydra to human being is, unfortunately, very limited because in highly developed organisms normal functioning of many important organs and tissues is determined by the presence of postmitotic cells (neurons, cardiomyocytes, etc.) which actually cannot be replaced.
