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.
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.
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...
