For the First Time, Organ Regenerated Inside a Living Animal
ananyo (2519492) writes "Scientists at Edinburgh University have successfully persuaded an organ to regenerate inside an animal. As they report in the journal Development, they have treated, in mice, an organ called the thymus, which is a part of the immune system that runs down in old age. Instead of adding stem cells they have stimulated their animals' thymuses to make more of a protein called FOXN1. This is a transcription factor (a molecular switch that activates genes). The scientists knew from earlier experiments that FOXN1 is important for the embryonic development of the thymus, and speculated that it might also rejuvenate the organ in older animals. They bred a special strain of mice whose FOXN1 production could be stimulated specifically in the thymus by tamoxifen, a drug more familiar as a treatment for breast cancer. In one-year-olds, stimulating FOXN1 production in the thymus caused it to become 2.7 times bigger within a month. In two-year-olds the increase was 2.6 times. Moreover, when the researchers studied the enlarged thymuses microscopically, and compared them with those from untreated control animals of the same ages, they found that the organs' internal structures had reverted to their youthful nature."
Are the organs really that young or is it just new growth of old tissue?
to humans.

Those hyper-intelligent pan-dimensional mice sure are good at getting humans to do all the work to cure mice of all disease and aging.

That's organ hypertrophy for you, nor organ regeneration. With age, the thymus undergoes atrophy but it's still there. Whatever "youthful nature" means for a cell studied under the microscope.
Cue the "What will we do with all the people?" arguments.

Don't care. If the organ is restored to youthful function, as at least the linked summary indicates, then this is a big deal.
Specifically, this appears to be very different from (say) cardiac hypertrophy, where the heart grows larger but works less efficiently. In this work, the "rejuvenated" thymus not only gets bigger, it produces more T cells -- in other words, it works more like a youthful organ.
FOXN1 protien inreases organ size, return youthful vigor! No prescrpton needed! CLIKC HER NOW!!

At a certain point, after much testing and fussing, and deciding that such treatments are safe for humans we will be confronted with a simple fact. We can not afford the medical technology that we already have. How can we get these breakthrough treatments for the people that need them? Almost all seniors would need quite a few items repaired. Check out the price of testosterone gels for senior males. That stuff runs $1,400 per month and they would be on it for years, Imagine the price of getting some good stem cells customized for your heart or brain or kidneys. The multimillion dollar medical patient is about to become the norm.
Can you imagine the tragedy if the likes of Michael Bloomberg and Koch Brothers could remain useful and continue accumulating wealth?
We've been on to them since 1998.

i want to see the day where the doctor give me a pill and i leave the hospital with a new kidney :)

I'm not sure what's the point of having larger organs than normal.

So, all the other times they were regenerated inside dead animals?

This isn't the first time an organ has been regenerated inside an animal.
It's been documented for several years that after a partial liver removal, humans can regenerate livers.

Let me see if I understand the process they've found:
1. Genetically engineer a mouse to respond to a drug
2. Administer the drug
3. ???
4. Profit!^W Publish how you have discovered a cure for aging. (Non-GMO humans need not apply. Side effects may include premature death.)

Can you truly see no difference in the idea that the government should provide tax-funded handouts to all, and the idea that the government should facilitate a system in which everyone has a realistic opportunity to acquire the assets necessary to provide for themselves? True, both must restrict the excesses of the robber-barons, but that's about all they have in common.
