Stem cells can be found in bone marrow, umbilical cord, and the peripheral bloodstream.
stem cells
Stem cells can be harvested by destroying human embryos.
Embryos...
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.

The umbilical cord has stem cells in it. Baby teeth are another possible source of stem cells.

There are two other sources of hematopoietic stem cells--bone marrow and peripheral blood

bone marrow and bladder in adultsembryonic cells alsoStem cells from embryos and ones from bone marrow.
The main similarity between embryonic and adult stem cells is their ability for self-renewal.
they could potentially grow new organs
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
a stem cell from an animal / humans [but still not proven possible] may be used to produce clones.
