to stop killing embryos
They do not treat all diseases. For the diseases they can treat the embryonic cells can provide replacements for the failing (or entirely missing) cells that due to their absence cause the disease.
Scientists typically obtain embryos used for stem cell research from fertility clinics. These embryos are typically donated by couples who have undergone in vitro fertilization (IVF) and have chosen to donate their unused embryos for research purposes. It is important to note that stem cell research follows strict ethical guidelines and informed consent is obtained from donors.
Human cloning is currently not legal in the United States. Federal law prohibits the creation of cloned human embryos for any purpose, including reproduction or research. There are strict regulations in place governing the use of human embryos in scientific research.
because they are taken from embryos. The embryos used in these studies were created for reproductive purposes through in vitrofertilization procedures. When they were no longer needed for that purpose, they were donated for research with the informed consent of the donor.
The first concern is the destruction of human embryos to extract stem cells. Pro-life activists argue that embryos are a form of life and should be allowed to live. Another argument is that stem cell research can devalue human life as it can lead to consent of reproductive cloning.
Positive: Screening can identify embryos that will develop severe genetic diseases, thus allowing doctors and parents to choose a course of treatment or to terminate the pregnancy. Negative: The power to screen embryos may result in people screening for relatively trivial things or in extreme cases, eugenic selection of only embryos possessed of specific traits.
Frogs are mostly used in research because they are the closest living relatives to man that are easy to raise in captivity and their embryos are easily handled when doing studies.
The Catholic Church is against using human embryos for research, specifically stem cell research, for a few reasons: 1. Many embryos are the product of abortions. The Catholic Church does not sanction abortion nor does it believe it justifiable to use aborted babies for research because of the convenience. 2. The Church believes that at the moment of conception every human being is given an immortal soul. Because of this, every human being has an eternal destiny. Children that die in the womb because of violence, accident or natural complications are to be treated with the dignity proper to a human being. The Church does not condone treating embryos as lab samples. 3. There have been significant developments in alternate methods of cell research that makes it unnecessary to use embryo cells for research. Until these ways are exhausted the Church sees it as unnecessary to take the current path. Bottom line is the Church never condones doing evil to achieve good. The source of many of the embryos combined with their treatment in the lab as raw human matter is considered evil by the Church and It will not give Its support to such undertakings despite the potential benefits.
Cloning is asexual reproduction. There are all kinds of research that can be done on stem cells without creating any actual embryo or causing the gestation of an embryo in order to give birth to a new organism.

From the mother's body, - they are inside it while they are embryos.
