I think that the human embryonic stem cell (hESC) research should be continued since if

this research is successful, it can be beneficial for all human beings and encourage further

development. Because hESC is pluripotent, it can transform to any other types of cell. Thus, it

can be used to cure many diseases that are incurable, such as type-1 diabetes and genetic

disorders. Many people will gain from the hESC research. Moreover, the research also

encourages many further developments. For instance, Shinya Yamanaka has successfully

transformed human skin cells into induced pluripotent (iPS) cells, which function exactly like

human embryonic stem cells. Thus, I think the hESC research should be continued.

I think that scientists should not use discarded embryos from fertility clinics to conduct

human embryonic stem cell research since this source of embryos addresses the concerns of

those who do not want to see embryos destroyed for research purposes. Scientists can use

induced pluripotent stem cells instead. In this way, they can avoid many controversies of using

discarded embryos from fertility clinics, and the iPS cells act exactly like the hESC. Although

the embryonic cells are going to be destroyed, many people still think that destroying embryos

for research is violating sanctity of life. Therefore, using iPS cells can solve the ethical problems

that bring from using hESC for research, and the iPS cells are easier to obtain than hESC.

Therefore, since people have many concerns and controversies of using discarded embryos for

research, I think it is better to use iPS cells instead.

I tend to use Consequential ethical approach. I determine my approach through looking to

the consequences, outcomes and situations. Consequential ethical approach tends to seek the best

and the most useful
