Success with stem cells

i think Bush h e i s against research for stem cells.president Obama will lead research for this.

I think you should learn to operate your keyboard better than my cat could before presuming to pronounce on things you obviously know nothing about. Your illegible posts are just about on my last nerve.

I believe Svante is from one of the Nordic Countries of Northern Europe.

He does a far better job than I would trying to communicate with him is his language as I only speak English, American, Canadian and I can get by in Australian in a pinch.

That's a fairly standard fallacy of perfect competition. As I have mentioned time and time again, even orthodox economists reject the premise of perfect competition, as evidenced by the development of monopsony theory. Unsurprisingly, the potential for utility maximization lies apart from the potential for profit maximization.

Is it just me, or has Agna just achieved bureaucratic doublespeak nirvana?

I believe I achieved that a while ago. Shall we discuss the impossibility of viable general equilibrium or any legitimate Walrasian auctioneer status?

Science, like anything else, should pay its own freight.

If stem cells, embryonic or otherwise, are the supposed miracle cure for anything and everything, then investors who smell a profit will provide the proper capitalization for research.

You can always tell where the REAL potential is by where the private venture capital is. If a line of research MUST have government funding to even exist, it's a waste of time.

Of course you can. And when you see a government program that goes over budget by a factor of ten, does not achieve it's primary objective, and takes twice as long as planned, you understand why people hate government programs. The program referred to was the Lewis and Clark Expedition. All too often, in exploration, be it scientific or physical, what we find by accident, is more important that what we were looking for.

There have been numerous medical success's using adult stem cells for treatment.
Can anybody provide a link to show successful medical treatments that used embryonic or fetal stem cells?
I'm starting to think science should focus on what works.

I ask the same question.

What are the similarities and differences between embryonic and adult stem cells?

Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.

Embryonic stem cells can be grown relatively easily in culture. Adult stem cells are rare in mature tissues, so isolating these cells from an adult tissue is challenging, and methods to expand their numbers in cell culture have not yet been worked out. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies.


...


Scientists believe that tissues derived from embryonic and adult stem cells may differ in the likelihood of being rejected after transplantation. We don't yet know whether tissues derived from embryonic stem cells would cause transplant rejection, since the first phase 1 clinical trials testing the safety of cells derived from hESCS have only recently been approved by the United States Food and Drug Administration (FDA).

Scientists hail gain in human embryonic stem cell research


"The goal of this research was to create patient-specific embryonic stem cells with the patients' DNA for the eventual use in cell replacement therapy," Egli told CNN.

He said the motivation for the research was to eventually cure diseases such as Parkinson's, diabetes and many other illnesses.


This new study, published in the journal Nature, shows researchers have finally succeeded in creating human embryonic stem cells. They weren't perfect though because they have too many chromosomes -- 69 instead of the usual 46 -- making the cells suitable for research purposes only, not actual treatments.

The doctors did offer an alternative: Bonnville could become the first human to receive experimental stem-cell therapy to revive his damaged heart tissue. They went ahead with the procedure, the results of which could turn the stem-cell debate on its head.

Doctors at William Beaumont Hospital in Royal Oak, Michigan, used a procedure that, if successful, could eliminate some of the controversy surrounding the medical use of embryonic stem cells, as well as the practice of therapeutic cloning.

"We're very excited because we think that there's already been substantial recovery of cardiac function," said William O'Neill, Beaumont's chief of cardiology, regarding Bonnville's progress.

The teenager's therapy began Feb. 17 with a four-day regimen of a drug that stimulated the production of stem cells in his blood. On Feb. 21, doctors harvested Bonnville's stem cells. Using a heart catheter, they transplanted the stem cells into the artery that supplies blood to the front of the heart.

He was discharged about a week later and is now recuperating at home. His doctors say they have never seen a recovery like his.

Did you bother to read your own frigging article, you silly bitch, or did you just grab on to the fraudulent headline and run with it? From your article:

The teenager's therapy began Feb. 17 with a four-day regimen of a drug that stimulated the production of stem cells in his blood. On Feb. 21, doctors harvested Bonnville's stem cells. Using a heart catheter, they transplanted the stem cells into the artery that supplies blood to the front of the heart.

They used HIS OWN STEM CELLS. And since the guy in question was a teenager, I'm going to guess he wasn't an embryo, ergo they would not have been embryonic stem cells.

Sit down and have a nice cup of shut the hell up until you can say something intelligent.

2003



However, the Beaumont procedure doesn't require embryonic stem cells at all, because the necessary cells were taken from Bonnville's own blood. The experimental therapy also eliminates the need for another intensely debated technique: therapeutic cloning.

The assumption that therapeutic cloning is key to the success of embryonic stem-cell therapies (none of which has yet been shown to work) has permeated both the stem-cell and cloning debates.

By creating a cloned embryo of a patient and extracting stem cells from it, scientists believe they might get around the body's tendency to reject new cells as an immune response.

Since Bonnville's own cells were used in the procedure, rejection isn't a concern, O'Neill said.

"They're his own cells, highly concentrated, and we put them into the damaged area," he said. "We wouldn't anticipate anything different than we would normally."

Other studies have suggested that simply injecting stem cells into a damaged area might be enough to instigate tissue repair. But most of the work has been done with younger stem cells taken from embryos or aborted fetuses.

This appears to be the first piece of evidence that stem cells taken from someone as old as 16 have differentiated so effectively. Still, O'Neill says he's not sure the results could be duplicated in older people.

"We know that based on age, older people have less recovery of heart function," he said. "It's very possible this is age-dependent."

Other researchers said the results look promising, but that it will take time to determine whether the treatment is a success.

"I think it's extremely hopeful," said Dr. Neil Theise, a stem-cell researcher at Beth Israel Medical Center in New York.

Dr. Sam Dudley, a cardiologist at Emory University in Atlanta who is also involved in stem-cell research, said that even if Bonnville continues to improve, it may be hard to know whether it was thanks to the therapy, and, if so, how it worked.

"I think this is a wonderful thing that they did," Dudley said. "We have to (proceed) judiciously because we need to know a little bit more what we're doing."

The fact that Dimitri Bonnville didn't have any appealing alternatives to the stem-cell therapy made the decision to go with an experimental treatment easy, his father said.

August 24, 2010


In the last days of July, the Food and Drug Administration gave the green light to a clinical trial that has been nearly a decade in the making. The federal agency approved a test of some of the first fruits of human-embryonic-stem-cell research, in a new therapy that could help patients recover from spinal-cord injury.

The trial will be the first to use embryonic stem cells in human beings. The plan was developed by the Geron Corporation, a drug company, which financed the development of the cells in a lab at the University of California at Irvine.

Such partnerships took on even more importance this week, after a federal judge temporarily stopped the National Institutes of Health from financing embryonic-stem-cell research because it is tied to the destruction of embryos. The decision sent shock waves through the scientific community. It also makes arrangements like the one between Hans S. Keirstead, the researcher at Irvine, and Geron an attractive alternative to relying on federal money.

And yet another article that pretends that adult stem cells and embryonic stem cells are the same.
I'm still waiting for the proof that embryonic stem cells can actually cure anything. We already know that adult stem cells can and do.
Articles like the above just muddy the waters and folk like Valerie fall for it.
