Medical Board Suspends Oregon Doctor For Stem Cell Treatments …

Oregon Medical Board has issued a rare emergency suspension of a Eugene physicians license after the doctor conducted experimental stem cell treatments on patients.

The board considers Dr. Kenneth Welkers medical practice an immediate danger to the public.

Welker can appeal the suspension, issued Thursday. He did not return calls from The Associated Press on Friday, nor did the clinic at which hes employed, Oregon Optimal Health.

According to his online biography, Welker is a trained surgeon who quit his practice to pursue alternative medicine in 2007.

In May 2013, the boards suspension order says Welker injected processed stem cells into the spine of a 62-year-old woman, and was confused when she began to sweat and feel tingling in her extremities.

Stem cells, unlike other cells in the body, have two distinct characteristics. They can renew themselves through cell division, and they are not specialized in the way that muscle cells or brain cells are. Under certain conditions, they can be induced to transform into organ- or tissue-specific cells.

In 1998, researchers discovered how to derive stem cells from human embryos, and in 2006, they determined how to induce some specialized adult cells to take on the genetic characteristics of stem cells. These are called induced pluripotent stem cells, or iPSC.

iPSC have long been used to treat cancers such as leukemia and lymphoma its what doctors are using when they do bone marrow transplants. The cells are being studied for everything from heart disease to diabetes, but its too soon to know if these approaches are safe or effective.

Advocates of alternative medicine have heaped praise on the possibility of using iPSC to treat a variety of maladies. Texas Gov. Rick Perry, for instance, had stem cells taken from fat in his own body, grown in a lab and then injected into his back and his bloodstream during a 2011 operation to fuse part of his spine.

But scientists have questioned the safety and wisdom of Perrys treatment, especially because it was not part of a clinical trial in which unproven therapies are tested in a way that helps protect patients and advances medical knowledge.
