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.
Pluripotent stem cells.
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting 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.
The three types of stem cells are Totipotent, Pluripotent and Multipotent. Edit By Camden Stevens: there are actually four- Totipotent, Pluripotent, Multipotent, and Unipotent stem cells. Toti, Pluri, and Multipotent are all embryotic stem cells, which means they occur in the embryo before the child is actually born, then pluripotent and multipotent last until adulthood. Then unipotent stem cells occur through adulthood to the rest of the life.
Bush said that embryonic stem cells can be extracted from human embryos as thong as they are left over from fertility treatments and were donated to science.
On June 19th 2006, former President George W Bush vetoed the embryonic stem cell research bill. This bill would reversed the Dickey Amendment which made it legal for federal money to be used for research where stem cells are derived from the destruction of an embryo.

There are three different types of tissue stem cells in the body. They include the tissue stem cells also known as adult stem cells, embryonic stem cells, and induced pluripotent stem cells.
