Two broad types of stem cells found in people are adult stem cells and embryonic stem cells.


The scientific term for adult stem cells is somatic stem cells. They are found in umbilical cord blood, bone marrow, blood, peripheral blood stem cells, menstrual blood, skin, teeth and placental tissues.

Embryonic stem cells are taken from donated human embryos that are not needed for invitro fertilization. These are only used with the permission of the parents. The blastocysts grows in the petri dish for six months, producing a cell line, which contains millions of stem cells.

Today the most common medical treatment using stem cells are transplants to patients with serious diseases of blood, such as leukaemia or lymphoma.
