A New Biopaper for Organ Printing 125

Posted by ScuttleMonkey from the 98.6-off-the-presses dept.
Roland Piquepaille writes "Organ printing is an emerging branch of medicine which uses healthy cells to repair a damaged or diseased organ. But as its name implies, this new medical technology needs ink, paper and a printer. Now, a new hydrogel -- or biopaper -- developed at the University of Utah has been selected by the National Science Foundation (NSF) to speed up this process. This five-year NSF study will initially try to print blood vessels and cardiovascular networks. But its real goal is to build some complex organs, such as livers or kidneys. This technology can potentially help millions of people waiting for transplants."

      Well, in a sense, we already are. I know Glen (the creator of the biogel in the linked article), and one of the problems they are going to have is determining the identity of cells within complex tissues that were previously thought to be homogeneous. It turns out that kidneys (and many other appearing homogeneous tissues) are actually incredibly complex. New methodologies in tissue identity and tracking need to be applied here and we have the tools. Check out some of the images generated by these tools here [utah.edu].

      They do mention in the article that complex organs such as a liver or a kidney are a long way off. It does sound like science fiction, but if they can at least start with what they claim :

        "I believe in five years we're going to be able to print simple organs, such as a cardiovascular network or a urethra,"

      I think that it is a good step to actually growing organs for people. Just because something is science fiction today doesn't mean it will be in the future.

      Of course, the longetivity and compatibility of the organs is always the largest hurdle when dealing with transplants in general. Just like in transplants, these two issues will be paramount in new endeavors. My question is, how long do these organs really last? That is the largest question on whether this will stay science fiction or if it will become routine procedure in 10 years. If the complex procedure only lasts 5 years, it may be more worthwhile to get an actual transplant.
      • Yeah, I just thought about that too. I would imagine rejection would be much lower if they use one's own cells and thus the immune system wouldn't have to be artificially weakened through pills - you don't get that benefit through organ farming....
      • Depends.
        This technology can potentially help millions of people waiting for transplants.
      • It's your own cells, so it's compatible. Longetivity should be likewise OK.

        A bigger problem might be printer resolution. An eye made with lots of jaggy edges or dithering is not going to be a nice eye, though it would fill the hole in your head.

When injecting stem cells into existing parts of the body, they nicely migrate according to chemical signals and begin transforming into the appropriate type of cell.

  • Arteries will not be simple to print (Score:5, Informative)

    by Morris Schneiderman ( 132974 ) on Monday November 07, 2005 @09:04PM (#13975422)
    Starting as a geek with 25 years of software development and project management, I've spent the past year applying that project management experience to looking at the interaction between the heart and the arteries. And I can tell you that arteries are not simple.

    First, artery walls are seven (7) layers thick. That's seven distinct types of cells and structures to print.

    Second, the old theories viewed arteries merely as passive pipes connecting the heart to the capillaries. But as far back as 1733, Hales understood that the arteries are pumps. He saw them as passive pumps, expanding when blood was pumped into them, and then contracting due to their elastic membranes after each heartbeat. Observations made 50 years ago by McDonald and now being reinterpreted in light of additional data strongly suggests that the arteries are active pumps. (I'll spare you the details, but it adds at least an order of magnitude to the complexity of the 'image'.)

    Third, there are at least two sets of nerves that run through the outer wall of the arteries, the sympathetic and parasympathetic. These nerves seem to exert control over the contraction and relaxation of the smooth muscle in the artery wall. We don't yet understand the intricacies of the processes that control the phasing of those contractions and relaxations, but degredation in those control processes seems to be the mechanism behind the development of heart failure. While these nerves will have to be 'printed' and 'wired up' (no USB connections), it's not clear that their connections to the brain are the only contol paths. There may well be other, currently unknown, 'jumpers' that are needed. Closed source software isn't the only thing with undocumented APIs.

    So, there are reasons why teflon tubing is not being used as a replacement for arteries. And those reasons will make it hard (but not necessarily impossible) to print arteries. I wish them well. But don't hold your breath. Do take care of your body - it's the only one you have and will continue to be so for quite a while yet.
