A Pen That 3D Prints Bone Right Onto Patients

RATE THIS! +52
Posted in Medicine on 13th Dec, 2013 01:50 AM by AlexMuller

One of the greatest promises of 3-D printing is that we'll one day be able to print organs on-demand. Need a new liver? There it is, at the push of a button.

 
Anticipating that future, scientists from the University of Wollongong in Australia have created the BioPen, a tool that lets physicians more or less draw new bones on people through 3-D printing. The pen is loaded with so-called "stem cell ink," a batch of human cells that can form new bone. Another second substance, a polymer, then seals the area so the stem cells can do their work in peace. You can see why this is promising: if someone loses parts of bone in an accident, a tool like this pen could apply a fix directly to the problem area.
 
We've seen 3-D printed bones before, actually, but this device could give a little more precision. It's yet to undergo clinical testing, so it still may be a while before it hits the market, but if and when it does, it'll have some company.

This an idea that should be supported- bioprinting efforts are ongoing, funding is coming and there are already companies established based on this idea.

Yes, there is funding. Critical illnesses can already be successfully treated today by replacing cells, tissue or organs. Government, industry and the research establishment have been working hard to improve methods and procedures for artificially producing tissue. Bone is one example

In labs around the world, bioengineers have begun to print prototype body parts: heart valves, ears, artificial bone, joints, menisci, vascular tubes, and skin grafts. Reply

Yes, in the longer term, the printer could help build organs for transplants or repair. Since the printer can put stem cells in a three-dimensional pattern, it could build a small “patch” for a heart or kidney that would be made from stem cells cloned from the patient. Reply

When you want to engineer an organ you have a zillion conditions and requirements to fulfil-a very complex situation Reply

This area of technology is very important. 3 D bio-printing will allow creation of more accurate human tissue models which are essential to drug development and toxicity-testing outside animals. Since the majority of drug discovery is targeting human disease, it makes sense to use human tissues Reply

This is developing fast-great. There are several factors that are driving the trend of bio-printing: more sophisticated printers, advances in regenerative medicine, refined software. .....

Fast indeed. In two decades, 3-D printing has grown from a niche manufacturing process to a several billion industry, responsible for the fabrication of all sorts of things: toys, wristwatches, airplane parts, food and is now aiming to create organs Reply

Yes, but printing biomaterial is an entirely different ball game - this is a big deal Reply

It seems that many aspects of regenerative medicine are still to be perfected before any human trials start. Another 10-15 year?

3D printing is already known in cardiovascular innovation. Branched vessel structures can be generated by Inkjet printing technology.

Yes, for blood vessels, there is suitable bio-inks for 3D printing technology. The transparent liquids consist of components from the natural tissue matrix and living cells. Reply

To be honest,I think these are a ltitle tame in comparison with the type of thing you pull off for Batman pieces.I say boil down the characters to their essence like you do with Bats,Deccie. Reply
