Immortality in jellyfish?

Likely referring to 

Turritopsis dohrnii, the immortal jellyfish, is a species of small, biologically immortal jellyfish found in the Mediterranean Sea and in the waters of Japan. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.

Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die. In nature, most Turritopsis are likely to succumb to predation or disease in the medusa stage, without reverting to the polyp form.

 

Is there an any chance of this capability be harnessed in benefit for humans?

Not really. Brain is the problem. Complex network of a number of cells.

Can clone people easily enough. But only your genes that are continuing.

Why would you want to turn people into foetuses and have them grow up again?
