Cell Potency: Totipotent vs Pluripotent vs Multipotent Stem Cells | Technology Networks adult stem cell potency

Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.

Jun 28, 2012 · Adult Stem Cells: Potent Stuff! Blog entry June The short answer is “potency.” Potency in stem cell terms refers to the ability of a specific stem cell to make different mature cell types. The going theory (and I really haven’t seen much in the literature to change my mind) is that the older a person is, the less potent their stem.

If the beneficial effect of adult stem cell transplantation is a trophic effect, what are the mechanisms? Is donor cell-recipient cell contact required, secretion of factors by the donor cell, or both? What are the factors that control adult stem cell proliferation and differentiation?

Potency specifies the differentiation potential (the potential to differentiate into different cell types) of the stem cell. Totipotent (a.k.a omnipotent) stem cells can differentiate into embryonic and extraembryonic cell types. Such cells can construct a complete, viable organism. These cells are produced from the fusion of an egg and sperm cell.
