They can be formed to recreate any cell in the body. Because they are new cells, they have not yet been permanantly made into a certain type of cell (for example Brain cells, liver cells, skin cells, etc...) and are thus moldable. Scientists believe they can use these, replicate them and designate the cells to form a certain type of cell. This, in theory, can allow them to create limbs or new organs when people require them, but they cost a pretty penny.
There are many different types of stem cells, from many different types of sources such as: embrionic, fetal, adult, peripheral blood, umbilical and pluripotent.
Stem cells represent an exciting area in medicine because of their potential to regenerate and repair damaged tissue. Some current therapies, such as bone marrow transplantation, already make use of stem cells and their potential for regeneration of damaged tissues. Other therapies are under investigation that involves transplanting stem cells into a damaged body part and directing them to grow and differentiate into healthy tissue.
Stem cells have the potential to become any kind of cell. With the right research, doctors may be able to use stem cells to repair or replace organs that have been damaged by disease or injury. We have transplants for some organs, but people with transplants must take medications to suppress their immune systems for the rest of their lives. Such medication would be unnecessary if we can grow a new heart or kidney from a person's own stem cells.
Scientists are working to grow a large number of stem cells to help people with degenerative diseases become healthy once more.
It's currently restricted by law in the United States.
Regenerative Medicine
genetics
It is illegal to use humans. Rats and mice are inexpensive and easy to keep.
Totipotent
Researchers use embryonic stem cells to study diseases such as Parkinson's. They can be used to develop cures.

adult stem cells are to big to study.
genetics
There are two types of stem cells: Embryonic Stem Cells and Adult Stem Cells.Embryonic stem cells are isolated from:The blastocystAdult Stem Cells are isolated from: Bone MarrowFats or Lipids (Known as Adipose Tissue)Blood
It is illegal to use humans. Rats and mice are inexpensive and easy to keep.
Totipotent
Scientists believe stem cells from human embryos could hold the key to treatments and cures for disease. Basically it is a debate about stem cell research.

You could get bovine stem cells from a cow. These could be useful if you are trying to study stem cells themselves, however most stem cell research is for the purpose of human medicine. For medical applications bovine stem cells would not be of much use as they are significantly different from human stem cells.
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.
Stem cells would be crucial in learning how to cure some genetic diseases and growing organs for people who need organ transplants.
Cells function in different parts of the body. Stem cells are cells that have not yet formed into a perticular kind of cell; i.e.- red blood cells, white blood cells, skin cells, etc. Scientists can "coax", if you will, the stem cells into any type of cell that they want/need. With stem cells, a person with, say, a blood disorder has the opportunity to go for a stem cell treatment, which would inject the cells into the affected part of the body. The scientists would have, by this point, made the stem cells into the type that the patient needs. With the new cells, the person has a very good chance of having the disorder cured.
