Stem Cells From Fat Create Beating Heart Cells
Amenacier writes "Melbourne scientists recently discovered that stem cells isolated from human fat could be made to turn into beating heart muscle cells when cultured with rat heart cells. This discovery may lead to the use of fat stem cells in repairing cardiac damage, or fixing such cardiac problems as holes in the heart. It is proposed that culturing the stem cells with rat heart cells allows them to differentiate into heart muscle through signals from the rat cells. In the future it may be possible to inject/transplant the stem cells into the damaged area and have them naturally differentiate into the type of cell required, with only the natural stimuli provided by surrounding cells, without any danger of rejection by the body. Quoting: 'The next step is to implant the human heart cells onto the damaged heart of a laboratory rat to see whether they repair the heart. Then they would be trialled in higher species such as sheep and pigs before human applications could be considered. Clinical application could be five years away ...'" The Age has a multimedia treatment (Flash) of the discovery.
Nah. We've already got those.
my fat cells are killing my heart cells
might as well sacrifice a few of them to give back what they took
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
That from the fat of the overweight American comes the cure for heart disease brought on by his poor diet!
With two thirds of Americans overweight, this is promising news.
The society for a thought-free internet welcomes you.
Pabst Brewing co., is that you?
That McCain/Palin don't get elected if you want this kind of research to continue.
no matter who gets elected in the USA, future research won't be effected by this. Unless said president decides to attack Australia. Please do more research next time before making off-hand comments about politics.
Hey, I tried Pabst Blue Ribbon for the first time the other day, and it wasn't too bad. Everybody always talking about how bad it is, but they should just give it a try.
Beer, and this includes your favorite beer, is something you grow to like. In reality beer is nasty shit and we all know it. We just learn to tolerate a certain flavor, and we like to stick to what we learned to tolerate. Many may deny it, but in reality all we really want is the alcohol, or one to have the taste to remind us of the alcohol.
Yep, I just said that a beer didn't taste bad, and then went on to say that all beer tastes bad.

So the plan was to get the entire world to bulk up and then sell their fat back to them as a means to save them...
the first rule of stem cell research is you don't talk about stem cell research.
There's a lot of questions that have to be answered here - it's not as simple as they say it is. Adipose-derived stem cells are definitely nothing new - adult stem cells are widely studied and commonly used in bioengineering labs. The problem is that translating this into a clinically useful tool is far from reality, and there are a lot of fundamental issues that have to be resolved before something useful can be made:
In Australia things might happen faster, but for the US, getting this particular system running is full of regulatory issues and problems that aren't going to be easily addressed - 5 years is frankly impossible. I'd say 10 years, and that's AFTER they get all of the animal studies up and running. Ah, and it will cost tens of millions of dollars, if not hundreds of millions.
When "research" includes such things as "discovering that other nations exist," we are well and truly fucked.
Even more so, since this is not embryonic stem-cell research (to which McCain, Palin, and many other Christians object), but rather adult stem-cell research (to which only Jehovah's Witnesses and Christian Scientists object, as far as I know).
Personally, I have yet to read of truly successful research with embryonic stem cells (because they are generally rejected by the recipient), whereas many large advances have been made with adult stem cells (since the donor and the recipient are the same person, rejection is eliminated) -- for men at least, pluripotent cells have been found in the testicles, so that any type of cell could be produced without having to use embryonic stem cells. I also recently saw a report about a person with congenital heart disease who was apparently cured by an injection of his own bone-marrow stem cells.
So I suppose my question would be why the intellectual elites want to spend their research monies on embryonic stem-cell research that is more expensive, less successful, and morally questionable to a large sector of society, rather than on research in areas where successes keep coming, the cells are available without moral complications, and the costs are in general lower. A cynical person might think that it's all about getting drug patents and getting money out of the consumers and padding their own checkbooks...
I did saw "stem cells extracted from human farts..." had to re-read it a second time wondering where the science could ever stop
