Most of the current news that covers stem cells usually refer to either stem cells in the fetus, umbilical cord or, bone marrow. However, all tissue contains stem cells.
Currently, stem cells are being harvested from the umbilical cord or bone for transplant therapy.
A recent theory with alot of evidence backing it is that cancers arise from deviant stem cells. Much of the work has been centered on brain tumors, breast cancer, melanoma (skin cancer) and prostate cancer. Elimination of these cancer stem cells may be the key to a cure.

New cells are produced in the bone marrow, but some stem cells survive outside of there as well.

There are adult stem cells and embryonic stem cells.
adult stem cells -
An adult stem cell is an undifferentiated cell found among differentiated cells in a tissue or organ, can renew itself, and can differentiate to yield the major specialized cell types of the tissue or organ. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found. Some scientists now use the term somatic stem cell instead of adult stem cell. Unlike embryonic stem cells, which are defined by their origin (the inner cell mass of the blastocyst), the origin of adult stem cells in mature tissues is unknown.
embryonic stem cells -
Embryonic stem cells, as their name suggests, are derived from embryos. Specifically, embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro—in an in vitro fertilization clinic—and then donated for research purposes with informed consent of the donors. They are not derived from eggs fertilized in a woman's body. The embryos from which human embryonic stem cells are derived are typically four or five days old and are a hollow microscopic ball of cells called the blastocyst. The blastocyst includes three structures: the trophoblast, which is the layer of cells that surrounds the blastocyst; the blastocoel, which is the hollow cavity inside the blastocyst; and the inner cell mass, which is a group of approximately 30 cells at one end of the blastocoel.

blood and bone marrow. If you get a stem cell transplant, they harvest those from your peripheral blood (autologous) or bone marrow (analogous)

Mostly bone marrow and spleen.
