Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them.
Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.
Stem cells also show promise for treating some diseases that currently have no cure.
Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.
Adult Stem Cells
Stem cells can turn into any type of cell before they become differentiated.
Embryonic Stem Cells
Mesenchymal Stem Cells (MSCs)
Induced Pluripotent Stem Cells (IPS)
The full classification includes

Controversy
There has been some controversy about stem cell research. This mainly relates to work on embryonic stem cells.
