There are adult stem cells. Bone marrow transplants are stem cell therapy. But there are few of these cells in an adults body. They also can only make the type of cell from where they are taken. A stem cell from the liver can only make liver cells. They are also hard to grow in vitro and are more likely to contain DNA problems.

Fetal stem cells can make almost any type of cell in the body. They contain few if any DNA errors. It is these cells that are highly coveted and it is these that are used predominantly in places like Mexico where the laws are more lax.

And one last point. If it was adult stem cells they wanted there would have been no debate. I dont know how old you are, but in the 90s the debate of stem cells raged exactly because they were talking about using fetal stem cells.

So ya you can but no they dont usually except bone marrow treating leukemia.
