Cardiac Patch for a Broken Heart
Roland Piquepaille writes "People who suffered from heart attacks or other heart failures often need transplants because their hearts are essentially non-functioning. But imagine what would happen if it was possible to engineer living heart tissues to fix these broken hearts? This is what bioengineers at Columbia University Medical Center in New York City are starting to make. According to HealthDay News, their patches for broken hearts are made of heart tissue grown in the lab. Right now, animal trials are just starting and it will take at least a decade before human trials begin. But when these living bandages are ready for cardiac care, they'll have the potential to save millions of lives in the world every year."
the heart will work again for a little bit, but other major organs that iteract with the heart will cease to function correctly, and the new patch will somehow allow the heart to be more vulnerable to viruses.
...patches will only be available on the first Tuesday of every month. Any severe heart attacks occuring between these so called "patch days" will have to wait.
This is all very interesting. If and when they do manage to come out with the cardiac patch I would suspect (as well as hope) that they would have patches to fix other tissue types (striated, smooth, etc).
I'm also wondering if it was possible to use cancer research to produce an anti-cancer... No I do not mean a cancer cure, but an infection of healthy living tissue. Is it possible to introduce healthy tissue into a body or system and have it spread in a cancer like fashion repairing everything in its path? That would be way too cool!

FINALLY, there's hope for Dick Cheney! Now if only they knew how to grow a brain for Georie.
My son's bladder was born on the outside - and needed it reversed. His surgeon at the time got to the point before putting it back in the body but then something happened: he moved on. However his new surgeon - Dr. Atala - is a guy renowned in the field for tissue re-engineering. My son's bladder is now back on the inside but one of the exciting things that is happening right now is that he has more of a chance of getting his bladder completely fixed out now than at any other time. His bladder is too small... and needs augmenting. The "traditional" way has been to augment the bladder with intestine tissue (often needing an extra channel for urine excretion), but Dr. Atala has managed to figure out how to augment the bladder - at least AFAIK in animals - with engineered tissue based on the original bladder. And the guy was attracted to our area to continue his research.
I'm excited about this growth area in medicine - not as a doctor or as a medical professional (sorry I am squeamish at blood) - but as a parent of a child who stands to benefit enormously from this kind of research. I hope and pray that this kind of stuff - patching hearts, augmenting bladders, mending broken organs in general - all develops and gets to the point of viability in time.
Mark.
