stem cells that is causing all the controversy comes from embryonic tissue they haven't taken on a final role so can have the potential to become a different type of cell such as a cell for a heart or liver but stem cells are found in human organs

Depends on what kind of stem cells you are looking for.
As other posters have mentioned, hematopoeitic stem cells can be found in the marrow of flat bones. There are liver stem cells ("oval cells") in the liver. There are gut stem cells at the base of the crypts... there are skin stem cells, etc etc..
The key difference is that all of those stem cells are limited in what they can differentiate into. The advantage of embryonic stem cells is that they are totipotent- meaning that they can be induced to differentiate into any type of tissue, not just a few types.

Usually in the bone marrow. However, these stem cells can't do much else other than form different types of blood cells.
Stem cells taken from the embryo are the ones that can differentiate to form any type of tissue.

Any number of places. They are in the blood, umbilical cord, bone marrow. University college hospital london have a good section about stem cell treatment - might be worth a look x

The stem cells in a human adult are usually found all over the body. they primarily attend to the function of cell replenishment and repair. these adult or somatic stem cells can be sourced from a simple tissue of a human body for research.

They can also be derived from human embryos as well as the previous answers that were given. The adult tissues reported to contain stem cells include brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin and liver.

Bone Marrow
Umbilical Cord

in adults it can be found in bone marrow . they r called haematopoietic stem cells.

pluripotent stem cells can be found in the bone marrow

Bone marrow I think.
