Stem cells that are harvested from mature human tissue.
Stem cells found among differentiated cells in a tissue or organ.
Also called non-embryonic stem cells - any kind of stem cell that has been taken from an adult source. Adult stem cell sources include bone marrow cells, umbilical cord blood cells and peripheral blood stem cells (PBSC). Adult/non-embryonic stem cells are completely without controversy because they are taken from post-birth individual donors who are unharmed by the harvesting process. No embryos or unborn are involved in their collection or transplantation. Meanwhile, adult stem cells offer a gift of life to patients with leukemia, other cancers, anemia and a host of other serious illnesses.
Stem cells in the developed organism; these include the various types of multipotent and unipotent stem cells, but to date do not include known pluripotent stem cells.
Undifferentiated cells in a tissue. These cells can grow into any of the types of specialised cells in that tissue.
undifferentiated cells that have the potential to become a limited number of specific cell types. These multipotent cells are found in small quantities in umbilical cord blood and adult tissues. Adult stem cells that have the ability to develop into cells outside their own lineage have not yet been found.
Somatic stem cells found in adult e.g. bone marrow stem cells
Cells that can renew themselves and differentiate into a limited number of specialized cell types. They replace and renew damaged tissues.
Stem cells found in different tissues of the developed, adult organism which remain in an unspecialized state. These stem cells can produce specialized cell types of the tissue from which they came, i.e., a heart stem cell can give rise to a functional heart muscle cell, but it is still unclear whether they can give rise to any different cell type of the body, also called somatic stem cells.
Derived from the umbilical cord and placenta or from blood, bone marrow, skin, and other tissues.
Multipotent stem cells that are found in adult tissue.
