Well, there are controversial views with regards to stem cell research.
Some would say that stem cell research is important as it has the potential to save many lives and greatly improve our medical knowledge.
However, many would argue that it is 'playing God' and that we should not be using stem cells, as it is not natural - not how things were meant to be.
Doctors can and do use stem cells from adult bone marrow but they have to be an exact match to the recipient.
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.
embryonic stem cells can differentiate into more types of cells
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
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.

embryonic stem cells can differentiate into more types of cells
well yes....and no
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.

Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. ... Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. Embryonic stem cells can be grown relatively easily in culture.
Stem cells are those which could make up new tissues. Eg. bone marrow stem cells make up blood organelles. Adult stem cells could be used to make tissue that could then be transplanted into human beings.
