generally speaking progenitor cells are dervied from stem cells. the fate of
progenitor cells are more determined than stem cells and as a consequence they
can only differetiated into a few cell types. while stem cells have much
more potential to differentiate into various cells and organs. it's all about
potential.

No.
Now, it's suggested to use somatic stem cells concept than adult stem cells.
As far as I know, progenitor cells are of less differentiation
potential(multipotency, just many progenies but not all), while stem cells are
of pluripotency (All of the progenies). So in this matter, PC is considered
more committed, determined, or differentiated than SC. However, most time ppl
find adult stem cells which are really progenitor cells.
One also needs to clarify precursor cells (or simply precursors),
