Embryonic stem cells that are pluripotent can develop into any type of cell.

an over view of the embryonic stem cell therapies in use?

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.

embryonic stem cells can differentiate into more types of cells

An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
