I’m equal parts fascinated and concerned about this sort of thing. It’s incredible what science is capable of while, at the same time, I wonder if there are adequate limits on such advances. These researchers seem to be responsible (limiting the growth to a certain number of days, applying for permission to extend that limit in the future etc.) but I have a feeling that somewhere there is a scientist whose professional ethics are a little less robust.

tonyedgecombe• 8 years ago

It's a good point although if you are really worried about the ethics then the way we rear animals for food dwarfs this.

roryisok4• 8 years ago

And the ethical concern that often goes unmentioned is hope the rearing of animals for food has left barely any room on earth for wild animals. If anyone can find that biomass breakdown chart it's pretty scary. Something like 90% of the biomass on earth is human food

adrianN• 8 years ago

What are your ethical concerns about this experiment? I don't think sheep with a human pancreas need to be treated differently from sheep with a normal pancreas, ethically speaking. We're not talking about fiddling with the sheep's brains.

docdeek2• 8 years ago

I guess it is more a feeling that it'll start with a pancreas and then we'll figure out a way to make other organs, and maybe some human life after that. Perhaps it shouldn't concern me - if I would be fine with a pancreas or a kidney grown in an animal, why not (eventually) a human life in an animal? - but it is still a worry for me right now.

limits

Humanity is just a infant. It's way too early to talk about limits, really.

>but I have a feeling that somewhere there is a scientist whose professional ethics are a little less robust.

Butchers seem to have made peace with a few things. The same with their clients, lamb eaters. Let's be honest, at some point we cut corners; diabetes is the new epidemic. Most people, at least in the developed world, can stuff their faces with cheap (and poorer you are, more empty) calories.

wombatpm• 8 years ago

This would be a cure for TYPE I diabetes, not TYPE II. The difference? TYPE I aka juvenile diabetes is an autoimmune disease where the islet cells of the pancreas are targeted and you no longer produce insulin. TYPE II is where the cells in you body become insulin insensitive. TYPE II can be reversed with diet and exercise in its early stages.

Why are they both called diabetes? The consequences are the same, high blood sugar levels causing damage to eyes, kidneys, and peripheral blood flow in limbs. This can cause blindness, kidney failure, and limb amputation and eventually death.

lawlessone• 8 years ago

I don't think these are the same kinds of diabetes.

With the kind you get from over indulgence your pancreas is still functional, you just have insulin resistance.

I believe this is to help the other kind of diabetes where you produce no insulin.

walshemj• 8 years ago

Try asking some one whos on the list for a transplant a large number of which die every year because of lack of donors.

antisocial• 8 years ago

Spot on, I just needed a toe fracture to rethink morals and ethics. I am all for humane treatment of animals, am an almost vegan myself, if you can just raise the cute animals in a humane way, I won't object the progress on this development.

bertil2• 8 years ago

The main non-theoretical concern over such chimeras is that they could host disease variants and transmit them to humans.

You don’t want to catch foot & month disease. They typically should not leave sterile conditions because of that potential threat. Therefore, having cell-bundles grown in petri dishes and vats is probably preferable than an autonomous live animal.

That takes off a bit of the moral conundrum of having cute animals raised to be sacrificed. Vegetarianism and veganism are getting traction fast, so that could become more controversial. SciFi has explored the possibility of having conscious humans raised for their organs, so you could see an increased awareness in the next decades.

Pica_soO• 8 years ago

Alastair Reynolds introduced us to hyper pigs, beating up humans for a dark past.

On the other hand Uplift made it our duty to raise as many creatures to full awareness as possible.

Which author are you referring to exactly?

Pigo3• 8 years ago

I have to agree. Of course, I've never had a child dying from organ failure, so I don't think I'd be quick to judge. But there is also a part of me that thinks humans are meant to die, and this kind of science is fueled a lot by fear of the inevitable. The powerful are trying to stave off death until the singularity they believe will happen, and the lengths those kind of people are willing to go scare me. But maybe I'm just thinking that because I watched Altered Carbon.

bobthechef• 8 years ago

While we sympathize with people who have dying children or are dying themselves, being in that position can in fact cause desperation and desperation can warp moral reasoning. In other words, being in a particular position does not necessarily put you in the best position for making the right decision, hence why we often value honest, appropriately competent, impartial advice.

W.r.t. to the moral dimension, there doesn't seems to be enough information in the article to make an assessment either way. If we're destroying fertilized human embryos to obtain stem cells to produce organs, then we are committing something categorically gravely immoral. If we're obtaining cells from the person needing the transplant and coaxing those cells into producing organ tissue, then the moral analysis will depend on contingent factors.

NeoBasilisk2• 8 years ago

Humans aren't "meant" for anything.

khazhoux• 8 years ago

There exists a future where you could conceivably eat a delicious lamb shank, while wearing a supple lambskin jacket, while your implanted pancreas and kidney process the meal, and all are sourced from the same animal.

chr1• 8 years ago

And some time after that a future where all of these are produced in the same factory from cell culture, and real sheep are rare.

JorgeGT• 8 years ago

But surely by that time we can have, say, electric sheeps, right?

roryisok4• 8 years ago

The same individual animal? Because that seems kind of weird for reasons I can't quite put my finger on.

I guess it would be less wasteful though. If you're going to butcher a man-pig to steal his pancreas you might as well use the leftovers. Would save hospitals money on catering too.

You know what, I've thought about it and I'm all for it

shezi• 8 years ago

Even today, very little is wasted when animals are slaughtered. And products made from animals find their way into a surprising number of end products. Here's some indication of whats going on from the Daily Mail (2009): http://www.dailymail.co.uk/sciencetech/article-1217794/From-...

The meat wouldn't stay fresh while you recovered from surgery. You could always freeze it, but then it's not quite as delicious.

That's all before you go to bed with your wife(male) who has a sheep-implant vagina.

A large dairy animal approached Zaphod Beeblebrox's table, a large fat meaty quadruped of the bovine type with large watery eyes, small horns and what might almost have been an ingratiating smile on its lips. 'Good evening', it lowed and sat back heavily on its haunches, 'I am the main Dish of the Day. May I interest you in the parts of my body?' It harrumphed and gurgled a bit, wriggled its hind quarters in to a more comfortable position and gazed peacefully at them.

Chimeras rather than hybrids, surely?

tmsldd• 8 years ago

Wondering... and if the cells also replace the brain and create a human-like intelligent sheep..

Piskvorrr3• 8 years ago

We've had talk of sheeple for decades now. Nothing new, methinks.

zombieprocesses• 8 years ago

It's a major ethical concern.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4928294/

Scientists/ethicists have been pondering whether stem cells and creating chimeras could lead to unintended consequences of affecting the brains of animals. Maybe even making them more conscious/intelligent.

ianai• 8 years ago

You know, or just start eating Whole Foods and plant based. Mayb a little cardio too.

lgils• 8 years ago

Type 1 diabetes is a genetic, autoimmune disease in which the the pancreas' ability to produce insulin is destroyed. Sadly, a little cardio won't help.

JoeAltmaier• 8 years ago

Other than the 'yuck' factor, what's the real objection to all this? Have folks read too much Science Fiction where it all goes terribly wrong? Maybe it'll be fine. Grow organs in sheep, use them on ill people, folks get better, have a mutton dinner to celebrate!

Seriously, we wear sheep's wool and skin, crack chicken embryos into our batter to make it bake up nice and firm, rub animal oils into our skin and armpits to smell and look better. But use them for real medicine and suddenly "Whoa there! Lets think about this some more?"

I'm all for continuing until there's a problem, which probably won't ever happen.
