Medical-research insiders know that embryonic-stem-cell[->0] technology is proving a dead end Dr. Bernadine Healy[->1], a former director of the home(a) Institutes of Health and once an ES-cell-research enthusiast[->2], calls it obsolete[->3]. But the Obama administration[->4] has opened wide the federal official funding floodgates the triumph of a big special-interest PR and lobbying campaign.
In fact, the research will line the pockets of a relatively a couple of(prenominal) individuals at considerable cost for the rest of us, since the funding promoter billions that wont go to more promising areas.
though ES cells have long been touted as the miracle just humble the road, researchers keep driving into big potholes. For starters, theres the rejection problem: Your body naturally attacks foreign cells, even off ones that might encourage you. So cell recipients must permanently use unplayful immunosuppressive drugs[->5].
Further, the cells have a nasty tendency to stick undersurfacecerous or to form teratomas[->6] kernel monster tumors. patch usually benign, these can grow larger than a football game and often contain hair and teeth. Yech!
Perhaps that problem can be solved someday, but even University of Wisconsin scientist James Thomson, the causality of the first human ES-cell line, says treatments and cures could be decades away[->7].
Conversely, adult stem cells[->8] (AS cells, meaning any naturally found stem cell not from embryos), are far more controllable (that is, easier to direct to buzz off the desired cell type) and have thus been saving lives for decades, via (for example) bone-marrow transplants. more recently, AS cells have treated illnesses[->9] including cancers, autoimmune disease, cardiovascular disease, immunodeficiency disorders and anxious degenerative diseases.
Plus, AS cells are often self-donated eliminating rejection problems (though AS rejection even from outside donors has turned out to be relatively minimal).
