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.

Controversy of stem cells?
The controversy surrounding stem cells arises out of the need to use stem cells from embryos which then get destroyed.
Will Jehovah Witnesses accept stem cells?
Witnesses do not believe in transplants of any kind, so they are against the use of stem cells.
Why is the use of embryonic stem cell controversial?

Why did doctors use embryonic stem cells?
Scientists use stem cells because they can generate healthy cells and replace disease ones. Plus they allow them to test and better understand disease and test new drugs for effectiveness.
Why are embryonic cells useful in medicine?
Embryos have special "blank" cells (e.g. stem cells) which serve no specific purpose, but can transform to become a different cell. As embryos grow and start to develop different body parts, these "blank" cells transform into cells that belong in that body part. These cells are being studied to try to apply them to treating diseases. For example, Sickle Cell Anemia is where a body produces red blood cells in a crescent shape that don't hold very much oxygen. Research is being done which seeks to use stem cells to replace the defective cells which produce deformed red blood cells. By doing this, scientists hope to cure or reduce the symptoms of Sickle Cell Anemia (which can commonly be fatal).

Which is the most likely reason that stem cell research is controversial?
Stem cells themselves are not controversial. There are different types of stem cells. Hematopoietic stem cells are the building blocks of blood. They are found in bone marrow and umbilical cord blood. They are currently used successfully to treat a number of different diseases. These are not controversial at all. Embryonic stem cells are controversial because they are obtained from embryos. Some people believe that using embryos to produce stem cells is unethical. The 'embryos' the anti-stem cell voice talk about contain about 75 - 200 cells, and are known as blastocytes. The cells are undifferentiated, meaning they as yet have no purpose. The Pro-Life movement refer to this collection of cells as a human being about 2-4 days after fertilization. Blastocytes are the best source of undifferentiated stem cells, and those used would be the excess discarded after IVF. They would generally be destroyed - why not use them to save human life? For Pro-Life- destroy these 'embryos' or use them to save life? Please explain your stance!

How scientists use stem cells to grow tissues?
Right now scientists are exploring many options with stem cells. Currently they can combine a persons body fat and some stem cells, mix them with some growth factors, and inject them in the patient. The body will then start to work with the stem cell, body fax mixture to regrow body tissue.
Why was the work of the American scientists in 1998 such a breakthrough in stem cell research?
they found a way to obtain stem cells without destroying an embryo - this removed all ethical concerns that were present for the use of embryonic stem cells

Can stem cells cure osteoarthritis knee pain?
Stem cells currently have no use in the medical industry but around the year 2025 scientists are hoping to be able to master the art of being able to turn stem cells to a human's own cells which could cure cancer and many other diseases.
Why do scientists use mouse and rat models to study stem cells?
It is illegal to use humans. Rats and mice are inexpensive and easy to keep.
What is the definition of stem cell research?
The research of undeveloped cells in aborted fetuses. These cells can be inserted into a diseased or abnormal part of a person's body and they can develop into whatever kind of cell they're surrounded by. This can repair and heal the affected area.
Why are people concerned about stem cells?
One source of stem cells is from aborted embryos - it's a non issue, as the embryo would have been discarded anyway and the stem cells wouldn't be harvested without the consent of the parent, but lots of right-wingers like to use that as a scare tactic to fight scientific progress. That's not even the only place to get stem cells from. Others worry that curing debilitating diseases is "playing god," and therefore bad.
