queensland researchers print three-dimensional body parts for implant, clinical trials could begin in 2015

Biotech officials say they want three implants in Australia.
Size printed body parts in just a few years.
Researchers have been printing implants for the past two years, and successful clinical trials have been conducted in Europe, the United States, India and Singapore.
Scientists were able to create a scaffold to replace human cartilage, tissue, and bones after scanning the patient\'s body.
Then send the information to a 3D printer using \"bio\"
This implant is made from a mixture of synthetic plastic and the patient\'s stem cells. The bio-
The price of 10 grams of ink is up to $5,000.
Once printed, the stent is implanted with a small amount of fat removed from the patient.
University of Science and Technology Queensland (QUT)
Associate Professor Mia Woodruff said the technology would greatly change the surgical implant industry.
\"It enables us to customize our patients.
Specific, anatomical-
The precise scaffold that includes cells and growth factors, which we can implant from the defective site, \"she said.
\"Once implanted, we can regenerate the tissue back to its original form.
Professor Dietmar humacher of Queensland University of Technology said that unlike conventional metal implants, printed synthetic brackets naturally break down in the body, just like stitches.
\"If you go to see a doctor today because you have a wound on your arm and he is sewing the wound with stitches, he will not ask you to come back. . .
\"These materials are degraded in the body through a process called hydrolysis,\" he said . \".
\"This means that water enters the polymer, breaks down the polymer, and then completely breaks down.
The plastic surgeon, Boris holsappell, said
The replacement of the fabric is much better than the metal implant.
\"Perhaps in the future, we will no longer rely on metal implants and their associated complications,\" he said . \".
\"We are able to specifically design tissue brackets with specific properties so that they can degrade over time and the patient\'s own tissue can take over its function for a long time.
\"Researchers will apply for the first Australian clinical trial next year.
Professor Hart Maher said the technology will one day make a breakthrough in organ re-engineering.
\"At the moment, we have not considered printing the entire kidney or liver,\" he said . \".
\"From the point of view of the spatial control we can place cells, our technology is already quite advanced.
\"But these cells that have been placed. . .
Entering a position requires not only the production of tissues, but also the production of organs.
\"From the perspective of printing technology, this direction of biology is much more complicated than what we have done.
\"Breast cancer survivors and researchers, Dr. Meha Whiteside, said she wanted to be one of the first to participate in clinical trials.
\"I had breast cancer when I was 28, and for nearly a year I had nothing in my chest,\" she said . \".
\"For me, there\'s silica
Great gel implant.
I have something there but it\'s not me and it\'s not perfect.
\"The current breast augmentation operation will only last about 10 years, and I have been close to 10 years --year mark.
\"I will lift my hand up. . .
At least in Australia, the first person to have this implant.
\"QUT is launching the first creature in the world.
