KILL 'EM ON PRINCIPLE:

Stem Cell News That Isn't Fit For Print: The mainstream media is ignoring promising news about adult stem cell research. (Wesley J. Smith, 12/03/2003, Weekly Standard)

Adult stem cell therapy would be almost magical. (A good analogy might be the common practice of donating your own blood for later use in your own surgery.) Instead of taking drugs to treat degenerative ailments such as Parkinson's disease or undergoing organ transplant surgery, if adult stem cell therapy works the way researchers hope, doctors would be able to harness the patient's own cells as potent medicine to rebuild damaged organs and body tissues. For example, a heart attack patient's bone marrow stem cells might be extracted, proliferated in culture, and then injected back into the patient resulting in the heart restoring health to damaged tissue.

EMBRYONIC STEM CELLS are another potential source for regenerative treatments. But, we pointed out, unlike adult stem cell treatments, ES cells cannot be used in human studies because of two fundamental safety issues. First, they cause tumors in animal studies. For example, in one recent experiment, ES cells were injected into a mouse in the hope they would rebuild the animal's damaged knee. Instead, the cells obliterated the knee by stimulating tumor growth. (More recently, an adult stem cell animal study successfully rebuilt joints without causing tumors.)

Second, using embryonic stem cells as a regenerative treatment--unlike adult stem cells--would introduce foreign tissues into the patient, perhaps stimulating the immune system to reject the tissues. "Therapeutic cloning" is supposed to get around this problem. The complicated procedure would involve the manufacture of cloned embryos of the patient who is to receive the stem cell treatment. The cloned embryos would be developed for one week to the blastocyst stage. At that point, they would be destroyed, and their embryonic stem cells harvested. (To date, researchers have been unable to successfully create cloned human embryos to the blastocyst stage.) These would then be proliferated in culture and eventually injected into the patient, the hope being that the tissues would not be rejected because the DNA from the cloned embryo and that of the patient would be nearly identical.

THE SEMINAR in which we addressed these and other issues was covered by the Louisville Courier-Journal. The resulting story ("Cloning Opponents to Make Major Push to Ban Research," November 23, 2003) never reported the actual content of our respective presentations. Instead, in a curious journalistic approach, cloning supporters from the Universities of Kentucky and Louisville were quoted extensively rebutting our wholly unreported remarks.

Most egregiously, despite our having emphasized adult stem cell therapies as an efficacious and less expensive alternative to therapeutic cloning, despite extensive citations referenced by Dr. Prentice from the voluminous successful adult stem cell experiments that have been published in the world's most prestigious peer-reviewed science journals, the Courier-Journal story contained not one word about adult stem cell research. Instead, readers were told that therapeutic cloning is the potential source of "treatments for diseases that afflict more than 100 million Americans," including "replacing malfunctioning neurons in the brain of a Parkinson's patient, adding insulin replacing pancreatic cells in diabetics and infusing muscle cells into the heart damaged by heart attack."

SADLY, this experience is typical of the establishment media's general approach of either not reporting or under emphasizing adult stem cell research successes.

The problem being doctrinal--abortion advocates can accept no limitations on the killing of incipient human life.
