Our findings demonstrate that RAC GTPase proteins are essential for injected stem cells to migrate into the correct location in the bone marrow.

Adult stem cells tend not to form tumors.

Stem cells are probably going to be extremely useful.

Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.

They demonstrate that you can isolate the equivalent embryonic stem cells by alternative methods that may not raise the ethical questions. I would say they also raise more questions than answers.
