Ethical Renection on the sources of Human Embryonic Stem Cell

Authors: Zhang, Xinqing., Fan, Chun-liang. and Chen, Qi. 

Abstract:

One of the key points for ethical review of human embryonic stem cell research is to examine whether the sources of obtaining human embryonic stem cell are ethical or not.However,the Ethical Guideline for Human Embryonic Stem Cel Research which has been issued in 2003,does not provide practical recommendation in detail for local ethical committees to conduct ethical review procedures.After examining several potential ethical problems involving the sources of human embryonic stem cell in current Chinese context,the authors put forward our key points for ethical review: First of all, although frozen spare embryos could be a major source for embryonic stem cell research in curent situation,researchers should not overuse or even abuse this kind of embryos.Secondly, the researchers should minimized the potential risks to the egg donors;and should not obtain eggs by coercion or inducement. Thirdly, in the process of use of aborting fetus for stem cell research, informed consent  is required from the pregnant or her family;and it is prohibited to let a person get pregnant in order to obtain an aborting fetus for stem cell research;Lastly, in the therapeutic cloning research, researchers could produce embryonic stem cells though somatic nuclear transfer technology, but the embryo ought to be destroyed within 14 days.
