Stem cell. Stem cells are cells which are not terminally differentiated and are therefore able to produce cells of other types. Medical researchers hope they can be used to grow specific tissues or organs.There are three types of stem cells: totipotent, pluripotent, and multipotent.A single totipotent stem cell can grow into an entire organism.nother controversy in the use of embryonic stem cells is the use of therapeutic cloning. This involves the cloning of early embryos from which stem cells are harvested, providing a larger source of the cells. Many see this as encouraging human cloning, which they think could be dangerous or unethical.
The most basic kind of stem cells are the cells that make up an embryo soon after an egg is fertilized. These stem cells divide over and over, eventually making almost all the different cells in the body. Adult stem cells, in contrast, are fully differentiated.. That means they are what they are and do what they do.hat they have in common is that they have the ability to make other types of cells. No other cell in the body can do that. Some stem cells can renew themselves and become virtually any cell in the body.
