Clusters of stem cells from the 3D printer  (Source:
Technique could help create artificial organs

Scientists may one day be able to address organ donation shortages and the need for immunosuppressant drugs for transplants by creating artificial human organs via 3D printing.

A team of Heriot-Watt University scientists, led by Dr. Will Shu, has successfully used 3D printing to create clusters of embryonic stem cells -- which could, at some point, be used to produce artificial organs.

The team used an adjustable microvalve as a 3D printing technique, where layers of human embryonic stem cells (hESCs) were built up to create clusters of cells. HESCs are derived from early stage embryos and are capable of transforming into any tissue in the body.

"We found that the valve-based printing is gentle enough to maintain high stem cell viability, accurate enough to produce spheroids of uniform size, and most importantly, the printed hESCs maintained their pluripotency - the ability to differentiate into any other cell type," said Shu.

The technique will use cloning to create hESCs that have the patient's own genetic programming contained, meaning that the artificial organ from which the hESCs are made will not trigger a negative immune response when transplanted.

Also, this method could produce artificial human tissue for drug testing purposes.

While 3D printing of cells is nothing new, previous techniques with human stem cells have failed due to the sensitivity of these cells.

It's not the stem cells that were created by printing! They were used to print clusters of cells.

Don't be silly. The majority of embryos used for this sort of thing are/were the result of IVF treatments which create many more fertilized embryos than the woman will actually need/use in order to create a statistically significant chance of at least one of them implanting successfully. The ones that don't implant/aren't needed are discarded anyways. So why not let them serve some useful purpose, since they're being created and destroyed regardless?

If and when people start getting pregnant or otherwise creating embryos *solely* with the express purpose of harvesting stem cells, then you *might* have a point. But that hasn't happened yet. And even if it had, attempting to completely block the use of embryonic stem cells would not be the way to solve that problem.

Can get embryonic stem cells from umbilical cords easily. Why that isn't talked about like crazy makes no sense to me.

Here's the thing about that, you have to pay the hospital an extra $1500+ in order for them to use the umbilical for stem cell research. Most people are going to turn that down. We need some way to get rid of that cost.

No, you are wrong.

You pay $1500 for YOUR baby's cord blood to be stored away for future use by YOUR baby. It is called cord-blood banking. The point of it is that if your kid develops some disease when he is 15, those stem cells with his/her DNA in it is available for use.

You can also choose to donate the cord material at no charge or have it disposed of.

They're similar, but not exactly the same thing. There are more than 2 kinds of stem cells. But even if embryonic stem cells are used as a research gateway, at some point we have to make the switch. Stem cells usage and application will eventually become mainstream like McDonald's french fries and there will be issues of scalability. OR we can just put our daughters on conveyer belts...

Not even mentioning tissue rejection... now *THAT* is something people always forget about when borrowing tissue from others. A lifetime's curse of immunosuppressive drugs.

You do know that Bush blocked the use, in research that has any government funding, of a handful of embryonic stem cells LINES that were created over 15 years ago. Scientists aren't horrible devils killing babies left and right. There are about 20 government funded embryonic stem cell lines that are used in research all over the country because the great thing about those lines, is that they reproduce very well and so there is no point it getting a new line of cells every single time someone wants to do an experiment (which is also costly). This way, a lab can just order the cells which are already cultured. Blocking the use of those lines actually encouraged new lines of embryonic stem cells to be made with private funding, thereby completely negating any "moral" reasons for banning the funding in the first place.

I agree. From the headline I thought maybe 3d printing technology had magically matured to the point where it could lay out cellular building-blocks in a way that created a new, living cell out of basic, not-quite-living components. That would be very cool, but is probably decades off at least.

Should be "Human Embryonic Stem Cell Clusters Created by 3D Printing with Stem Cells"

maybe i can start smoking again soon! if they can soon clone hearts and lungs.

The big question is, how long before they will be able to print out a whole human being? Kind of like in the movie The Fifth Element.

Perhaps this should be moved to the Defense section. That is where you will find one of the greatest impacts.

"Well Private Smith it seems you have lost an arm. No problem, we will print out a new one and with a few months of rehab you will be out there again killing the enemies of our country." Doctor America pats Private Smith on the shoulder with an arm still attached to it. When the doctor has left the room Private Smith starts to sob then sensors in his bed and room sense his mental state and release drugs into his IV and Private Smith relaxes and falls to sleep.

Yea we can keep our trained and heavily experienced cadre of volunteer soldiers killing who ever we point them at. And with ever more powerful psychotropic drugs they might not even care.

Not that there won't be a lot of good that will come out of this but the USofA is still at war after twelve years, twenty two years if you count the first Gulf War. Adults voted last year in this country that have never known a day of peace. If I am not mistaken this is the longest period of war in the USofA's history. And when the only two choices for political parties practice the exact same justification and strategy I see no end of war anytime soon.

As the French say. "You are fuch'ed."

More importantly and affecting even more people (for different reasons and at different stages in life)... replacement teeth!! Imagine everyone getting to 80 with new teeth, 0 cavities, very little darkening, ... Now that would be something!

PS: Just hope it wouldn't also be an added excuse for people not to have proper hygiene...

Thats f-ing nuts!

free limbs!

I look forward to the future when I can create extra limbs for myself. League of Four-Armed Body Builders, here I come!
