embryonic stem cells can differentiate into more types of cells
The controversy surrounding stem cells arises out of the need to use stem cells from embryos which then get destroyed.
You actually can use the stem cells from adult bone marrow in stem cell research. The practice has been gaining momentum with discoveries relating to mesenchymal stem cells.
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.
Stem cells are used for fighting off deadly diseases, and stem cells can help cell growth and reproduction.

One reason researchers prefer to use embryonic stem cells instead of adult stem cells because adult stem cells are often found in limited quantities, are difficult to isolate, and the older the donor, the less stem cells they have.

The adult stem cells are better than embryonic stem cells in a very few cases. One way they are better is that the adult stem cells can be transplanted back into the adult patient and grown. The body will not reject its own stem cells.
well yes....and no

The umbilical cord has stem cells in it. Baby teeth are another possible source of stem cells.

Embryonic stem cells are used to treat a variety of diseases. Stem cells also help organs and tissues repair themselves.
