WASHINGTON - Doctors have partially paralyzed patients with spinal cord injury, millions of human embryonic stem cells is the first attempt to test a promising but controversial treatment began, government officials announced yesterday.
Friday, announced Shepherd Center patients, 132 bed hospital in Atlanta, in the spinal cord and brain injury professional, after a goal from the hospital and Jie Luo Pake, California, is sponsoring research firm.
Seven of the hospitals participating in the test mainly whether the goal of treatment is safe on our website. The doctors perform tests to determine whether treatment of patients or recover, regain a sense of movement. No further data for the first time released patient.
The step of scientists welcomed the willingness to move from laboratory research to clinical application, and healed by patients' representatives and hope to patients. Although cells have been tested on animals, and some clinics around the world for the treatment of human embryonic stem cells, clinical studies through approval of government authorities and a careful evaluation of the strategy is first. After numerous delays, the U.S. Food and Drug Administration approved in July.
But that may be involved in each study of human embryonic cells, a moral argument that the cause of concern, many followers have been criticized. Some people think it is the experience that premature babies, some say they are ethical concerns many people about the risk of error if the disaster of the field test.
"If you do not know more about the clinical data of the little" I can say is, "said Steve Goldman neurology at the University of Rochester in New York, head of the department." For a variety of ... or from embryonic stem cells transplanted unpurified issues of security in the long term derivative. Time will tell. "
David Prentice, principal investigator for life sciences at the Family Research Council, said: "Geron is the share price to help, rather than science, especially in patients who take several years, strong evidence for safety or effectiveness of adult stem cells.. record of published evidence for effective treatment of spinal cord injury. "
Private research funding of fans think he was tested. U.S. Food and Drug Administration for laboratory experiments and animal studies, has asked a wide range of evidence to support the commitment of the cell and safety testing enough people.
"... We have a clinical trial for the field of human rights of therapy with embryonic stem cells, an important step," said Thomas B. Okarma, president and CEO of Geron, said in a statement. "From research and development, so that the inventive inherit the results of this service."
Donald Peck Leslie, Shepherd's medical director, said: "We are very pleased to participate in this study interesting to evaluate our patients with the medical progress of patients in this study, we expect interest to participate in research .. Clinical studies may help spinal cord injury. "
However, some scientists fear that if the patient is injured by the cells - or even "suggesting that these cells have not helped -. Then a terrible blow on the ground led Jesse Gelsinger, died in 1999 from ' a number of gene therapy experiment has been very popular in recent years the situation on the ground.
Security problems - the main concern may lead cancer cells - has led the FDA requested additional data in most Geron, until recently, to ensure that the cyst cells injected into mice, not as a threat.
