Stem Cell Team Grows Heart Valve

Posted on Apr 2, 2007

Opponents of stem cell research might want to reconsider their position if any of their nearest and dearest have ever had heart problems.  A team of British scientists has successfully grown a human heart valve from stem cells, an astonishing feat 10 years in the making.


Heart surgeon Sir Magdi Yacoub, who led the team, said doctors could be using artificially grown heart components in transplants within three years.

His researchers at Harefield hospital managed to grow tissue that works in the same way as human heart valves.

Sir Magdi told the Guardian newspaper a whole heart could be produced from stem cells within 10 years.

How close are they to giving Bu$h a brain. That would be a true breakthrough.

Rick Brown,

And I’d just be willing to bet my bottom dollar that my not having read the whole of the article isn’t what’s causing you to write, is it, Rickie?

You vomit:

“read the article before commenting.”

Which is always better rendered as “read the article before commenting, please”, eh? It fits so much better with the sweetness of someone who’s just never, ever jumped to a conclusion themselves.

H.C. Mooningham,

Yes, I’ve grown so used to reports that the Dr. Mengeles now in charge of our scientific establishment just can’t wait to sink their needles into the littlest and weakest among us that its almost de rigueur for me to expect the next of these announcements in hours. The sighs of relief that get heaved over such clarifications as the one you’ve made here, H.C., are now rare as hen’s teeth. I wish you well with your heart problem and I’ll say a prayer for you. Perhaps next time out we’ll learn that the cells needed to create a new valve for you can only be obtained from Chinese political prisoners or Gitmo detainees. Some get tired of watching the fulfillmemt of the utilitarian vision without sound and obvious pain, you know.

OK, so now that we know for sure that stem cells can give us new body parts,  what’s holding everything up?  Is it all this religious gibberish about a stem cell being as much a human being as, say, a child with heart disease who’ll die unless she gets a stem cell derived heart transplant?  Or is it that these Rapturists know that once the word gets out that stem cells offer us a chance to live forever (well, for at least a couple of wonderful centuries anyhow ) here on earth, not many of us are going to be interested in the pie in the sky?

Smug comments about the “opponents of stem cell research” fail to recognize that not all of such people are condemning ALL forms of stem cell research.

The heart valve was grown from stem cells taken from ADULT BONE MARROW. It sounds like a wonderful achievement, but why is the source of the cells being under-reported?

According to the GAO the increase in unfunded healthcare costs in 2006 was $4,600,000,000,000 or $2500 a month for every full time worker in the US. 

There is not only a moral but an economic imperative that we extend quality life span and quality career span to bring our economic system back into balance.  Otherwise, our economy will collapse and all those who feel like the previous commentor can take control in a new dark age.

The claim that life begins at conception has no basis in biblical scripture.  The fertilization of the egg was discovered only about 150 years ago, about the same time that evolution was discovered.  It seems that even the most rigid religions like to pick and choose those scientific facts which suit their needs.

Another postive scientific advance that benefits all of us everywhere. Excellent, simply Excellent.
What positive advance have any of the religions given us lately?
Frankenstein was a frelling story dumb ass.

Actually, the article states the stem cells came from bone marrow, not kids. And the idea seems to be to heal living people, not ressurect deal ones.

Perhaps John and the writer of the opening paragraph should have read the whole article which said that the stem cells used came from bone marrow. As one who has had two coronary artery bypass surgeries I found the article quite
interesting and promising.

Dr. Frankenstein made his monster with stolen body parts and gave it life with electricity; these guys steal a child’s stem cells and make a heart valve in a petri dish. Great minds think alike.
