There are mainly two types of Stem Cells, namely Embryonic Stem Cells and Adult Stem cells. A stem cell, for it's therapuetic values, should be bale to be expanded in any of the tissues of the body. To say in short they should be Totipotent or at least Plueripotent. The Embroynic stem cells are considered as totipotent by some writer (because they give rise to all the tissues of body) but plueripotent by some writer (because they could not give rise to Trophoblast Layer). These embryonic stem are usually used as an ideal stem cells and are expanded in culture for implications in medical use.
Adult stem cells
Pluripotent stem cells.
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.
Adult stem cells
The blood cell begin their lives in the bone marrow from a single type of cell called pluripotent hematopoietic stem cell.All the circulating blood cells are eventually derived from PHSC.

Totipotent
There are three types: totipotent, multipotent, and pluripotent. Totipotent: cells produced from the fusion of an egg and a sperm (embryo) Multipotent: cells that can give rise to a small number of different cell types--for example, bone marrow and brain contain this type Pluripotent stem: this type can produce almost all type of cells in the body; called 'true' stem cells I know there are Endothelial Progenitors, Germline Stem Cells, Hematopoietic Progenitors, Mesenchymal Stem Cells, Neural Stem Cells, Signaling Pathway, Embryonic Stem Cells, Cancer Stem Cells and Stem Cell Cytokines.
