It is not the news most people want to hear, but there are still only a few approved clinical uses of stem cell research. Some other applications of stem cells, for a range of conditions, are being investigated in clinical trials. A very large amount of research is ongoing globally.

The following points should make us aware of the limitations of embryonic stem cell research.
What Is Stem Cell Research? (with pictures) – wiseGEEK
What are embryonic stem cells?
At the very beginning of human life, the sperm and egg come together to form an embryo. After that embryo has grown for about 5-7 days, it contains embryonic stem cells which can be extracted. In this procedure, the embryo is killed. Similar embryonic-type stem cells can also be obtained from aborted fetuses. The extracted cells are then cultivated in a laboratory, replicating over and over again.

Is there a difference between embryonic stem cells and stem cell lines?
Scientists and moralists make the distinction between embryos, embryonic stem cells which are obtained by the killing of the embryo, stem cell lines which are developed from either embryonic or adult stem cells and products that are prepared from stem cell lines. There is a range of moral judgments relative to each of these specific aspects of stem cell research. In this pastoral reflection we are concentrating on human embryos and the moral prohibition against their destruction to produce stem cells for research.

What about the use of government funding for embryonic stem cell research?
Government funding would further encourage researchers to destroy human embryos. We must oppose the use of our tax dollars for research that involves the destruction of human life. When we enter the realm of public policy, each of us has an obligation to speak up and to take a stand for human life. We cannot proceed down the road of scientific development without sufficient moral reflection and ethical judgment.

Why is the extraction of embryonic stem cells immoral?
At the heart of the moral issue involving embryonic stem cell research is the fact that the embryo is killed so that the stem cells can be used for research – for the potential benefit of someone else. Embryos are human and at the very beginning of the process of life-long human development. Even though the human embryo is tiny at this point, as human beings and in solidarity with that life, we are not free to allow its use simply as a commodity for our convenience or benefit. As the Catechism of the Catholic Church teaches, “God alone is the Lord of life from its beginning until its end: no one can under any circumstance claim the right directly to destroy an innocent human being.” (). There are those who argue that, since hundreds of thousands of embryos frozen in fertility clinics are just going to be thrown away, it should be permissible to use them for research purposes. Such an argument ignores the truth that such embryos are human and should not be regarded as disposable in the first place. It is like saying that since one is going to die it is permissible to kill him or her. What makes this experimentation immoral is that in each case a human embryo in the process of human development would be intentionally destroyed for the sake of scientific experimentation. Immoral means can never be used even in achieving a good and noble end.
