Building New Body Parts

Building New Body Parts

<br>See what body parts scientists are cooking up in the lab.

NEED A BODY PART?
JUST HAVE SCIENTISTS MAKE YOU ONE. 
IT MAY SOUND TOO GOOD TO BE TRUE, BUT RESEARCHERS ARE DOING JUST THAT.
TONIGHT'S HEALTHCAST SHOWS US THE LAB THAT'S CHANGING LIVES RIGHT NOW AND COULD CHANGE MANY MORE IN THE FUTURE.
THIS IS THE LAB WHERE SCIENCE FICTION BECOMES REALITY.
YOU'RE LOOKING AT THE WORLD'S FIRST ENGINEERED URETHRA -- CREATED AT THE WAKE FOREST INSTITUTE FOR REGENERATIVE MEDICINE. FIRST - RESEARCHERS TAKE A VERY SMALL PIECE OF TISSUE FROM A PATIENT'S BLADDER. THEN - THEY GROW THE CELLS OUTSIDE THE BODY AND PUT THE TAILOR-MADE URETHRA RIGHT BACK IN THE PATIENT.
"Very much like baking a layer cake if you will, we do this one layer at a time."  DOCTORS WERE ABLE TO GIVE FIVE BOYS IN MEXICO WHO SUFFERED PELVIC INJURIES NEW URETHRAS.
AND CHECK THIS OUT!  RESEARCHERS ARE USING THIS PRINTER TO CREATE LAB-GROWN EARS. SO FAR - IT'S WORKED IN ANIMALS.
"We can make it match very closely to a native ear."
A C-T SCAN OF THE EXISTING EAR GENERATES A PATTERN THAT SCIENTISTS REPLICATE. A 3-D IMAGE IS MADE - THEN LAYER BY LAYER - THE MACHINE PRINTS THE EAR. 
IN ANOTHER PROJECT -- RESEARCHERS ARE ENGINEERING MUSCLE. FIRST -- THEY TAKE MUSCLE BIOPSIES AND ISOLATE CELLS THAT HAVE THE POTENTIAL TO MULTIPLY. THEY THEN SEED THEM ONTO A SCAFFOLD, TEACHING THE CELLS TO BECOME MUSCLE.
"Think of as exercise, as if you were exercising at a gym or something like that." 
THE NEXT STEP IS TO IMPLANT THE MUSCLE IN THE BODY - WHERE IT WILL REGENERATE AND REPAIR AN INJURY. THE NEW MUSCLE COULD HELP MANY AILMENTS INCLUDING NEUROPATHY, CLEFT PALATE, AND FACIAL PARALYSIS. 
"It's life-changing even in the simplest cases." 
THREE NEW BREAKTHROUGHS GROWN IN THE LAB - BUT MADE FOR OUR BODIES.
WHILE THE URETHRAS HAVE ALREADY BEEN USED IN HUMAN PATIENTS AND ARE CURRENTLY IN CLINICAL TRIALS, THE ENGINEERED MUSCLE AND BIO-PRINTED EARS HAVE NOT.  SCIENTISTS HOPE TO BE USING THEM IN HUMANS IN THE NEXT TWO YEARS OR SO.
HOPING THEIR WORK COULD ONE DAY HELP INJURED SOLDIERS.
RESEARCHERS AT WAKE FOREST HAVE ALSO TEAMED UP WITH THE MILITARY ON A FEW  PROJECTS.
