Stem Cell Research: Beyond Hype, Real Hope by the Family Research Council (http://www.frc.org). This public domain film is consistent with the teachings of the Roman Catholic Church, which state that the ablation of the inner cell mass (ICM) of the blastocyst, which critically and irremediably damages the human embryo, curtailing its development, is a gravely immoral act and consequently is gravely illicit. No end believed to be good, such as the use of stem cells for the preparation of other differentiated cells to be used in what look to be promising therapeutic procedures, can justify an intervention of this kind. A good end does not make right an action which in itself is wrong.a powerful video on adult stem cell research, showing its advantages over embryonic stem cell research. The public domain video offers useful, yet often ignored, information about adult stem cell research. We believe the information you'll see in the video is essential to making an informed judgment about the debate over this research. The question of stem cells is currently the dominant subject in the debate over biotechnology and human genetics: Should we use embryonic stem cells or adult stem cells for future medical therapies? Embryonic stem cells are taken from a developing embryo at the blastocyst stage, destroying the embryo, a developing human life. Adult stem cells, on the other hand, are found in all tissues of the growing human being and, according to latest reports, also have the potential to transform themselves into practically all other cell types, or revert to being stem cells with greater reproductive capacity. Embryonic stem cells have not yet been used for even one therapy, while adult stem cells have already been successfully used in numerous patients, including for cardiac infarction (death of some of the heart tissue). Stem cells are of wide interest for medicine, because they have the potential, under suitable conditions, to develop into almost all of the different types of cells. They should therefore be able to repair damaged or defective tissues (for example, destroyed insulin-producing cells in the pancreas). Many of the so-called degenerative diseases, for which there are as yet no effective therapies, could then be alleviated or healed. Public domain film. |
