Fitness Files: 3D printers could take transplants to new level

\"Read this.
\"My husband handed me the Smithsonian in May 2015.
Matthew Shaer\'s article \"body store\" extends the medical use of 3D printers and describes other strategies for organ replacement.
Fitness file in May 1
James Landman, chair of urology at the University of California, Irvine, suggested that future 3D printers can be used to produce disposable surgical tools.
In the Smithsonian article, shal visited the Wake Forest Regenerative Medicine Institute in Winston-Salem, New York. C.
, Look at the creatures that have the ability to print \"something alive.
\"Suppose the patient needs skin, bone, or bladder.
The modeling software scans an object to generate data for the printer, which uses biocompatible plastic \"to place continuous material coatings until three-
Form a dimension object.
\"For example, the article says surgeons cut a piece of skin humanely from pigs.
To replace the skin, the printer forms an interlocking structure or a skin scaffold, \"filled with a gel containing cells or proteins to promote the growth of cells or proteins.
When the scaffold is created, the cells on the pig are printed on it.
The structure is placed in the incubator, the cells multiply, and the \"printed\" skin is implanted into the pig.
\"Now there is a pig running around in the lab with a square skin printed on it. the color is a little different, but it is warm and vivid.
The future of mankind lies in the production of rejection. proof organs.
All the biological materials come from the patient, so what can be rejected?
When Shaer saw it, the machine printed a human ear.
Although the human body has not yet been implanted, the \"printed\" ears, bones and muscles have been successfully implanted in live animals. Dr.
Anthony Attara, a pediatric urologist trained at the University of Wisconsin and Harvard Medical School, said, \"We are approaching\" simple \"organs like skin, outer ear and test tubes --like trachea.
\"At present, the supply of organs required by hospitalized patients is not yet able to meet the demand.
Shaer quoted the United StatesS.
Department of Health and Human Services: \"20-
In this country, only one person dies every day while waiting for organs.
Atala said, \"the solution to the shortage of organ donors is to make replacement parts in the laboratory.
\"Atala is no stranger to the body parts of bioengineering.
Seven years ago, before the biographer
A stent was stitched for the human bladder replacement.
He used cells from a potential patient to reproduce them in the laboratory, applied them to the scaffold, and incubated the organs.
For the first time ever, the lab
The bladder was successfully transplanted in 7 young patients with cracked.
Seven years later, these organs are still functioning.
Despite the excitement around the functional bladder, the United StatesS.
The approval process of the Food and Drug Administration has progressed so slowly that the replacement bladder has not yet been approved for widespread use.
Slow FDA approval is just a problem with organ replacement.
Atala had trouble showing printed human kidneys in Ted\'s talk.
Some people say he\'s too hasty in acting for a printer. made kidney.
Although the kidney is indeed a common disease
Organs need to be transplanted, it is a complex combination of tiny blood vessels, millions of renal units and vascular systems fed by blood and nutrients.
PhD at the Texas Heart Institute
Doris Taylor, an expert in regenerative medicine, is experimenting with animal organs.
She reportedly stripped the muscle organs and other living tissues, leaving only the collagen matrix at the bottom.
The collagen matrix forms the sterile \"internal structure\" of the organ \".
The remaining structure after tissue removal was refilled by the patient\'s cells.
So far, Taylor has used decellular pig hearts to refill them with cow cells, which work with their own hearts in cattle.
Hey, this is the beginning.
According to the kidneys.
The statistics for tissue organ donation and transplant are 2014,123,175 people waiting for U for a life-saving organ transplant. S.
101,170 of them need kidneys.
Twelve people are waiting for a kidney transplant every day.
What would a non-relief family and patient experience?
Rejection of the kidney can print or take off cells.
People like Landman, Atara and Taylor have broken the limits of technological creativity in order to solve medical misfortunes and save lives.
