Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...
In mammals, only the zygote and subsequent blastomeres are totipotent, while in plants, many differentiated cells can become totipotent with simple laboratory techniques. A cell that can differentiate into all cell types of the adult organism is known as pluripotent.
Pluripotent stem cells are the descendants of totipotent cells and can differentiate into nearly all cells, [15] i.e. cells derived from any of the three germ layers. [ 17 ] Multipotent stem cells can differentiate into a number of cell types, but only those of a closely related family of cells.
The morphology and growth factors of these lab induced pluripotent cells, are equivalent to embryonic stem cells, leading these cells to be known as induced pluripotent stem cells (iPS cells). [75] This observation was observed in mouse pluripotent stem cells, originally, but now can be performed in human adult fibroblasts using the same four ...
Endothelial stem cells (ESCs) are one of three types of stem cells found in bone marrow.They are multipotent, which describes the ability to give rise to many cell types, whereas a pluripotent stem cell can give rise to all types.
Induced pluripotent stem cell (iPSC) lines are pluripotent stem cells that have been generated from adult/somatic cells. The method of generating iPSCs was developed by Shinya Yamanaka's lab in 2006; his group demonstrated that the introduction of four specific genes could induce somatic cells to revert to a pluripotent stem cell state.

Directed differentiation is a bioengineering methodology at the interface of stem cell biology, developmental biology and tissue engineering. [1] It is essentially harnessing the potential of stem cells by constraining their differentiation in vitro toward a specific cell type or tissue of interest. [2]
