Rat Limb Grown in the Lab

Now this is a true game changer. Can you imagine?

From the article:
"When electrically stimulated, the muscle fibers contracted with a strength 80 percent of what would be seen in newborn animals. What’s more, the blood vessels filled with blood.

“We have shown that we can maintain the matrix of all of these tissues in their natural relationships to each other, that we can culture the entire construct over prolonged periods of time, and that we can repopulate the vascular system and musculature,” said Harald Ott, MD, of the MGH Department of Surgery and the Center for Regenerative Medicine and senior author of the research paper, which appeared in this week’s journal Biomaterial."

God, I love science and research.

    Considerably more accomplishment than reading a book your parents told you to, and taking completely unsupported supernatural actions as gospel. Then backing into it being unerringly correct even though the basic text is filled with errors and centuries late human editorials. Yep, better than that.

    Notice the first mention of god is yet again from someone living in terror that the next facts will further demonstrate the scientific basis of magic.

    Nobody was hijacking anything.

    I think Scientific advances are wonderful, and to be lauded. Cloning, Stem Cells, all those things that intelligent scientists who study their entire lives to create is splendid. These advances however did not EVOLVE!!! They were created and designed.

    The possibilities for you to have your own heart clones or grown for replacement in the event of heart disease, provides opportunities people only thought of in science fiction 20 years ago. 20 years ago they would have called you unreasonable and lunatic crazy for even suggesting this could be done.

    Also your intolerance of other REASONABLE opinions by implying I am not rational and reasonable is, well shall we say, not a very open minded, and a bit dogmatic and reminiscent of other cultures that display excessive levels of intolerance for other views.

    Your comment is an insult to rational and reasoning minds and all the advances in health and human life they've allowed in the last century or so.

    This is warning 1 for highjacking a post.

    I'd bet on mid-century. Too late for me, but my children or grandchildren will have a much longer life than me. I think it's awesome.

    So a Rat limb was “Grown” in a lab. Wonderful accomplishment for the intelligent scientists that no doubt spent many, many years learning and developing the technology to do this.
    The potential is staggering.
    Now for my point. With all the chat I have seen over “No God”, and that “Big Bang” and “Evolution” caused all this, why don’t rats, automatically grow limbs back when severed? Why don’t people?
    I am surprised that these limbs did not just evolve out of nothing all by themselves with scientists standing around saying WOW look how that evolved.
    Universe and all life, and EVERYTHING with its intricacies and infinite complexities coupled with the TOTAL precision makes the Universe an incalculably value higher in complexity than all the efforts put into growing a rat limb, and people still have the audacity to think there is no intelligent design in our universe.
    May as well take a comment from Obama toward the scientists. “You did not build that!!!”
    Hence it must have evolved meaning these scientists were never needed or required to complete this.
    Every time I see major scientific advancement, my Belief in God is even further solidified, for if our universe was not Created by intelligence, then everything man does, man gets no credit since it must have simply evolved from nothing, simply because it “needed” to exist.
    To oversimplify this. 0 + 0 = 0. Zero * anything is still Zero.

    We are at the threshold of creating limbs and organs. Before the century is out, we will be extending life to much greater lengths than are possible today.

    I feel confident the Obamacare will cover the cost when this is developed.........well at least for the indigent and illegals!

    If I need one, I'm going to look pretty silly walking around on a rat leg. But hey, who am I to argue with science?

    This is incredibly cool. I did not understand why they had to use human stem cells as a substrate at one point...need to read more. This would indeed be the sort of thing that I could get involved in.

    First stage: Give everyone back the limb that failed to grow or had to be amputated.

    Second stage: Wings.

    Be nice to that rat limb...that may well be the start of a new generation of political leadership.

    A few of our new hires at FIT and I are working on very similar tissue engineering projects involving small blood vessels, bone engineering, and the tendon/bone interface. One of my students just submitted an article yesterday to the same journal. Biomaterials is a fascinating journal. A friend of mine and I took a Field of Dreams approach to starting a new Biomedical Engineering Department a few years ago. We built it, and in just a few years, that department has really blossomed. The success of that program is probably the biggest reason I haven't totally shrugged and may very well shrug in place. Going to work is a fun new challenge almost every day. Unlike all the other engineering disciplines, most of the big problems have not been solved yet in biomedical engineering, but the field doubles every 5-10 years!
