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 ...
Among dividing cells, there are multiple levels of cell potency, which is the cell's ability to differentiate into other cell types. A greater potency indicates a larger number of cell types that can be derived. A cell that can differentiate into all cell types, including the placental tissue, is known as totipotent.
Undifferentiated cells have not completed differentiation or specialization, thus retaining their cell potency and oftentimes being highly proliferative. [19] This is often the final cell state after the dedifferentiation process is completed and maintained, as cells become less specialized.
This stem cell can produce red blood cells, platelets, mast cells, dendritic cells, macrophages, lymphocytes, neutrophils, basophils, and eosinophils. Each of these cells have a different function, but they all work together as part of the immune system. Monocytes can differentiate into either dendritic cells or macrophages.
The interleukin 4 (IL4, IL-4) is a cytokine that induces differentiation of naive helper T cells (T h 0 cells) to T h 2 cells. Upon activation by IL-4, T h 2 cells subsequently produce additional IL-4 in a positive feedback loop. IL-4 is produced primarily by mast cells, T h 2 cells, eosinophils and basophils. [4]
In pharmacology, potency or biological potency [1] is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. [2]

It is commonly used as a measure of a drug's potency, although the use of EC 50 is preferred over that of 'potency', which has been criticised for its vagueness. [3] EC 50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/L.
