Printing Replacement Body Parts

Deep Penguin sends in a piece that appeared in The Economist a couple of weeks back about a developing technology to "print" body parts for transplant. "A US and an Australian company have developed the $200,000 machine, which works by depositing stem cells and a 'sugar-based hydrogel' scaffolding material. (The stem cells are harvested from a transplant patient's own fat and bone marrow, to avoid rejection down the line.) The companies are Organovo, from San Diego, specializing in regenerative medicine, and Invetech, an engineering and automation firm in Melbourne, Australia. The initial targets are skin, muscle, and 'short stretches of blood vessels,' which they hope to have available for human implantation within five years. Down the line, they expect the technology could even print directly into the body, bypassing the in-vitro portion of the current process."

      Greetings, fellow Type 1 diabetic!

      The reason pancreatic transplants aren't performed is that the chance of rejection is 100%. Your auto-immune system is already attacking anything that secretes insulin.. An insulin-producing organ from someone else would most assuredly not stand a snowballs chance in hell.

      There have been trials though. A few years back two diabetics here in Norway were "cured" by pancreatic transplants. They still had to live in virtual bubbles though because of the very strong immunosuppressive meds they were on. Despite the drugs, they only remained non-dependent on injections for about 12-18 months or so before the organ was put out of commission, so it's sadly not viable cure at all.

      Another procedure that could (in theory) work is to have your immune system and bone marrow destroyed chemically, then receive both a bone marrow and pancreas transplant from the same donor. The chances of finding both from a compatible donor aren't exactly convincing though, and there is of course the chance of the "new" immune system that follows your transplanted marrow will accept the pancreas but reject the rest of the body, promptly causing your death.

      There are some viable solutions though, like creating some sort of protein or something that to the immune system looks like insulin. Then administer huge amounts of this fake allergen to the patient to desensitize the immune system (similar to what is done with things like pollen allergies). The problem here is that no such substance exists as of yet, and you can't exactly give someone a superdose of insulin. Death isn't really the best solution, after all.. x)

      Another being looked into encapsulating cells (in this case, insulin producing beta-cells) in some sort of alginate made from seaweed. This allows insulin and nutrients to pass to and from the cell, while making it "invisible" to the immune system.

      Another seemingly promising solution is the theory that the immune system keeps attacking our beta-cells because of an on-going pain response triggered by the immune systems attack itself. Break the circle, and your body recovers most of it's insulin producing capability for at least a couple of years before something (like inflammation, etc.) causes you to need treatment again. I don't know how relevant this research is with regards to humans, but in animals injections of powerful anti-inflammatory drugs directly into the pancreas has reduced or abolished the animals insulin dependence for a year or two.

      Btw, I am as I said a Type 1 Diabetic. These days, I am playing around with a ketogenic diet, and I am currently taking 20 units of 12-hour insulin (Insulatard) each morning. That's it.

    What would, in my opinion, be truly interesting is if this printer device can be used with beef cells to produce artificial steaks (etc.). This could potentially remove the agricultural overhead of growing the meat, while reducing prices, increasing availability, dissolving concerns of inhumanity, and (possibly) skittering past some of the vegetarian reservations. Furthermore, there's no integration issues trying to put the product back into a live and functioning body!

      Even better, you can make extremely high-quality meat (quality from the point-of-view of taste), which normally requires torturing the animal and killing it young. Veal, Kobi beef, etc. comes from animals that don't exactly have wonderful lives, being penned up in cages so their flesh stays supple. Being able to artificially manufacture such meat would eliminate these problems, plus also make meat cheaper. Instead of paying high prices for the best cuts of meat, or getting nasty "stew beef" if you can't afford filet mignon, ALL beef could be filet mignon since it wouldn't cost any more to print the good stuff than the bad stuff.
