stem cells
That question seems a little vague to me. However, what I can say is that stem cells are used to aid human life. They are essentially cells that have not yet developed for a specific function in the body. Because of this, they can (put very simply) be maniplated to grow into a cell with a needed function in a human. This can aid in repairing spinal injuries, and possibly eventually cure para or quadriplegic patients. It is also involved prototypically in the development of insulin-producing pancreatic cells--aiding people with diabetes in a possibly permanent manner. So, essentially, yes--stem cells can absolutely affect human life.
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.

They have the potential to grow into a human being.
They are called stem cells.
Human Stem Cells Institute was created in 2003.
Yes, some stem cells do come from humans. The stem cells are taken from embryos. Animals also have stem cells used in research.
No. Stem cells occur naturally in the human body. However we are trying to clone stem cells to aid in there research.

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!

Yes and No. The only big difference is the procedures used in harvesting adult stem cells is considered legal and safe. There's no need to kill a human embryo. Adult stem cells can be harvested from cord blood or human bone marrow. But embryonic stem cells are able to make more kinds of cells than adult stem cells.
