There are different types of stem cells like totipotent, pluripotent, multipotent and unipotent that have specific uses in the research. Stem cells are present in different parts of the body, from where they can be harvested for further research. These include embryonic stem cells, adult stem cells, amniotic stem cells and adult cells induced as embryonic cells. Each

Umbilical cord cells are removed during pregnancy and stored in cryogenic cell banks as a type of protection policy for future use on behalf of the newborn. Compared to adult cells and embryonic cells, the umbilical cord is by far the richest source of stem cells, and cells can be stored up in advance so they are available when needed.

Cells produced by the first few divisions of the fertilized egg are also totipotent * Pluripotent stem cells are the descendants of totipotent cells and can differentiate into nearly all cells, i.e. cells derived from any of the three germ layers. * Multipotent stem cells can differentiate into a number of cells, but only those of a closely related family of cells.

The embryos that were no longer needed for reproductive purposes are donated for research with the consent of the donor. Many are against embryonic stem cells research because the embryo is destroyed after it is used, but otherwise the embryo would not be used and the embryo would have no benefit.
