Is it possible to regenerate our organs ?

In what is being hailed as a world first, scientists have succeeded in regenerating an organ in mice.
In the popular science fiction TV series 'Doctor Who' the titular Time Lord famously cheats death by regenerating his entire body and now scientists believe that it may be possible to do something similar with specific organs in humans.
In a recent breakthrough, a team of researchers at Edinburgh University managed to successfully rebuild the thymus of old mice so that the organ was restored to the same state as that seen in much younger animals. The process involved reactivating a pre-existing natural mechanism responsible for rejuvenating the organ that shuts down with age.

"By targeting a single protein, we have been able to almost completely reverse age-related shrinking of the thymus," said Professor Clare Blackburn. "However, before we test this in humans we need to carry out more work to make sure the process can be tightly controlled."

Living forever would be a total disaster to the planet earth! It is already over populated and cannot feed and support all its inhabitants as it is! We are born, we live the time that is given to us, then we die, that is the natural cycle of nature! The old pass on and the young take their place! If we were to even increase the average life expectancy by as little as 20 years let alone living for hundreds of years the entire world would collapse! There is a good reason we have an expiry date, im all for keeping people healthy and fighting disease, but this technology should never be allowed to... [More]

I have a friend that needs to grow a new liver.

The answer is YES. From sperm and egg can grow into a baby. Why can't we regenerate organ.

to heck with regeneration I would just be happy with having them (my organs) not go bad in the first place if my pancreas would make insulin like it was suppose to I would not be diabetic. regeneration will only make another one that doesn't work right to start with

Nah, you'd die of boredom, how many exciting moments happen in your life between the boring bits...and an organism born to a terrestrial environment would inevitably degrade in a space environment, let alone another biome... Heaps of research into this with some folks grabbing scaffolding from from some poor beggars corps and then stripping it in order to grow the recipients cells on it for transplant, others are using the body of the recipient itself to grow noses and ears... So who's got the money to live forever...either buying the tech or living long enough to benefit from Govt freebie hea... [More]

Stem cell research has people growing thumbs and ears these days. I think it is possible.

I'd like regeneration, it would be nice that if you loose an arm or finger, that you get a shot and it grows back. As to living forever, that would require fixing the issue of DNA damages that happen over time and eventually prevend cell reproduction. Totally different issue.

Different issue, true, but organ regeneration makes it easier and progress on the DNA and RNA issues are being made too.
