What type of Stem Cells are there?

There are two types of stem cells, the most common type of Stem Cell is the embryonic stem cell. Most embryonic stem cells are from embryos that develop from eggs that have been fertilized in a clinic and then donated for research purposes. They are not from eggs fertilized in a woman's body. The other type of stem cells is the adult stem cells. An adult stem cells is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ. The adult stem cell can renew itself and can differentiate to some or all of the major specialized cell types of the tissue or organ
