Male germ cells can be directly converted into other cell types:

Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. Their approach, described this month in the journal Stem Cells, may prove to be an effective alternative to the medical use of embryonic stem cells.

This is pretty nice experiment, especially since they used cells from mice that would glow green under fluorescent light in order to tell just what the cells were doing. Still lots of things to do, like showing it will work with human cells and what not.
Lots of good work coming out on stem cells. Maybe we will get even closer to human uses soon.
