OHSU Turns Mouse into Factory for Human Liver Cells

Biotech Science
Oregon Health & Science University researchers have figured out how to turn a mouse into a factory for human liver cells that can be used to test how pharmaceuticals are metabolized. The technique, published in the journal Nature Biotechnology, could soon become the gold standard not only for examining drug metabolism in the liver, which helps scientists determine a drug's toxicity, but also can be used as a platform for testing new therapies against infectious diseases that attack the liver, such as hepatitis C and malaria.

    Now, if they'd just turn a rat into a factory for fava beans.

      I was hoping that might be the case too.

      You'll probably need to have a mouse grafted on under your right arm though :(

    As they say, "Liver let die". Sorry.
  • I'm sure PETA, RSPCA etc will all have something to say about this. But i see it less immoral that we're using mice (at their expense) to end human suffering rather than to test cosmetics or kill simply because they're in our home. At least this kind of animal cruelty (as it could be construed) has a negating good karma benefit.
    • I'm sure the mouse feels terribly proud to be born with a fucked-up liver just so it can be repeatedly operated upon during its short but oh-so-meaningful life to provide alien cells to possibly save the lives of a few humans taking overpriced drugs from profit-obsessed corporations, to deal with conditions likely caused by their own overconsumption and excesses.

      Does it matter if they don't like it? Scientists are doing this kind of thing (research on mice/rats, not successfully creating a factory for liver cells) all the time. If those PETA people are going to let scientists do research on them, fine, but if not they should STFU and let these scientists help sick people get better - I think that's much more important than making sure that a mouse gets to run around in a sewer. It is a bit 'mean' to research on them like this, sure, but if you keep with that line of reasoning then you just shouldn't ever eat anything, because it's all alive at some point, and we have taken advantage of even the vegetables by planting and harvested their organs.

      "Angel of the Lord, what are these tortured screams?"
      And the angel said unto me,
      "These are the cries of the carrots,
      the cries of the carrots.
      You see, reverend Maynard, tomorrow is harvest day
      and to them it is the holocaust."

      like the tears of one millions terrified brothers
      and roared,
      "Hear me now,

      they have a soul.

      save our brothers...can I get an amen?"

        If PETA want to rally against Michael Vick, or against testing on animals for research into, say, cosmetics - I'll be the first to join them. But I hope they don't have a problem with research of this sort.

They would realize that if we were not testing on these mice the mice would never even have been born. Besides the fact it's a FREAKING MOUSE!

          • Holy crap! It's a good thing your playing Devil's Advocate because it sure sounds like you just equated (here in the USA, for example) people with black skin as animals.

            I think you may want to avoid doing that in the future, as most human beings I know find it offensive to be thought of as an animal. In fact, if you were to say that out loud, many places in the US, I really don't think you'd like the outcome. And I'm not sure I'd help you out.

It is a function of your own cultural biases that you equated the two and immediately took offense from that when what you should've taken offense at was the suggestion that abuse of slaves can be justified by the reason for their birth.

This is why a new drug takes about 10 years to be developed and it should stay that way, you cannot make this a parallel process without risking lives. Only when the severity of the disease exceeds any negative side effects the new treatment can have (e.g. very seldom high-mortality diseases) will the new treatment be set in at a higher s
