The embryonic stem cell research is likely to be free from the ethical controversy soon– such claim some researchers from the University of California, San Diego.
The researchers from the Research Ethics Program have claimed to have developed the technique of creating the artificial stem cell to behave like the embryonic stem cell. They have made a combination of four genes and a handful of chemicals unloaded into adult human skin cells to induce, or reprogram them to look and act like embryonic stem cells.
Thus the technique is expected to put an end to the moral and ethical debate over the use of embryonic stem cells.
Embryonic stem cells, and adult stem cells that can be induced to behave like them, are believed to be able to morph into any cell in the human body, such as the insulin-producing cells of the pancreas or the beating cells of the heart muscle. In theory, scientists could transform embryonic stem cells into healthy pancreas cells that could cure Type I diabetes by allowing doctors to replace a patient’s malfunctioning cells that give rise to the disease.
The San Diego researchers are trying to develop the alternatives to natural embryonic stem cells, such as using stem cells derived from unfertilized human egg cells. Along with easing ethical concerns, the artificial cells wouldn’t be as hard to come by as real embryonic cells, which have to be obtained from embryos left over from in vitro fertilization procedures and slated for disposal. The process usually requires the informed consent of the parents and is extremely expensive because the government has allowed only very limited federal funding for the work, leaving researchers reliant on hard-to-come-by venture capitalist or philanthropic funds. Also, because the artificial cells are exact genetic copies of the skin cells, in theory, the reprogramming technique would allow tissue made from the cells to be transplanted into a person to replace cells damaged by disease without fear of rejection.
Hopefully, the research is likely to get support from various organizations. For example, the California Institute for Regenerative Medicine, will distribute $3 billion in stem cell research grants over the next decade. In a statement, the spokesman from the organization, said the agency will continue to fund research using cells created by many different methods, including reprogramming adult stem cells and the growing of natural embryonic stem cells in labs.
Bioethicists agreed that all avenues of research should be pursued, but said it’s important that people scrutinize the process and ask the crucial questions when ethical and moral evaluations become necessary. There needs to be a balance between the concerns of medical science and the eagerness of terminally ill patients to get new treatments as soon as possible.

Embryonic Stem Cell May Be Free From Ethical Debate SoonJuly 9th, 2008 It seems the ethical debate over the use of embryonic stem cell is going to end. A new research, presented at the fertility conference in Spain presents the possibility of overcoming the ethical question regarding the use of it in near future.
The Choice of Destroying Unwanted Embryos Versus Curing Millions of Wanted & Loved HumansJanuary 15th, 2007 Stem-cell research is divided into two major camps: one focused on adult stem cells, while the other focussed on the controversial but most effective embryonic stem cells. Now there may be a third way.
The Door Should be Always Left Open for Embryonic Stem Cell ResearchFebruary 16th, 2007 All stem cell advances are welcome, but the door should be left open for embryonic stem cell research, advocates said Thursday. Opponents of research on embryonic stem cells say there is more potential for finding cures in research on stem cells that do not require the destruction of human embryos, which they object to on ethical grounds.
Breakthrough Study paves way for Stem Cell Research Overcoming Ethical IssuesJuly 3rd, 2005 Stem Cell Research would be revolutionized if post-natal stem cells can be used instead of embryonic stem cells. New research shows the way.
Embryonic stem cell lines needs stricter ethical protection ? Experts viewJanuary 29th, 2009 Though the bans on embryonic stem cell research are still on, but according to experts there are reasons to believe that there will be some executive order in the near future to reverse the Bush doctrine, the ban on federal funding for research on embryonic stem-cell lines produced after August 9, 2001. Thanks to Obama administration, already some closed doors for embryonic stem cell research are opening, but one can't deny that embryonic research is still carrying the million dollar "ethical protection question" like a satellite, which is a difficult task to be solved.
Revised ethical guidelines for embryonic stem cell researchSeptember 9th, 2008 The National Academies has released a revised amended ethical guidelines for research in the human embryonic stem cells. They have originally produced the guidelines to offer a common set of ethical standards for the responsible conduct of research using human stem cells, an area that, due to an absence of comprehensive federal funding, was lacking national standards.
Ethical debate over embryonic stem cells likely to get over September 27th, 2008 In a major research of its kind, the Harvard University stem cell researcher have found an alternative to embryonic stem cells. Thus it is likely to bring an end to the political and ethical tempest that has embroiled hopes for a new generation of medical treatments.
FDA To Design Blueprint For Human Experiment With Human Embryonic Stem CellsMay 1st, 2008 The Food And Drug Administration has finally agreed to permit human experiments with human embryonic stem cells and is working on the probable design necessary for the test. So far, biotechs have tested their spinal-cord drugs in animals, not people.
The embryonic stem cell research is likely to be free from the ethical controversy soon– such claim some researchers from the University of California, San Diego.
