Wake Forest Researchers Swap Skin Grafts For Cell Spraying 123

TigerWolf2 writes with this excerpt from a Reuters story carried by Yahoo: "Inspired by a standard office inkjet printer, US researchers have rigged up a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts. ... Tests on mice showed the spray system, called bioprinting, could heal wounds quickly and safely, the researchers reported at the Translational Regenerative Medicine Forum."

    Looks like it cuts down on scarring as well, and it seems that grafting requires adding an additional injury from the donor section. Seems sensible not to do this.

    Feeling bad about the rats is fine, it's normal.

    But it's disingenuous to say they want to burn animals for a living. What they do for a living is try to build a device that could save many lives and help many more reduce their suffering. They are required to test them on animals before humans, it's part of the job. It's not a part of the job they like, but it's necessary so they do it. Could there be a sadistic few? Sure, but it's unlikely. There are far easier and better paid jobs that allow you to be sadistic to animals than research assistant at a lab. Rats are cheap, you can buy or even catch all you like. Getting your PhD to satisfy your sadism toward rats is taking things a bit far.

    I would guess that most of them feel bad for the rats as well. But they can justify it with what they consider a higher purpose, reducing death and suffering. It might not be justifiable to you, but it is to them. It doesn't mean they like doing it.

    And I respect your opinion if you don't think it's worth it. Just please recognize that both sides of the argument have merit, and don't assume those that think differently than you on the issue are amoral or hate animals, but probably only disagree with you over which is more important.

    That's a great point. Humans are exactly like mice.
