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.

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...
