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 ...
Only embryonic stem cells of the morula are totipotent: able to develop into any type of cell, including those of the placenta. Embryonic stem cells ( ESCs ) are pluripotent stem cells derived from the inner cell mass of a blastocyst , an early-stage pre- implantation embryo .
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.
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.

Since embryogenic cells were considered totipotent cells based on their ability to regenerate or develop into an embryo under given conditions, dedifferentiated cells were generally regarded as stem cells of plant: "…we propose to extend the concept of stem cells to include embryogenic stem cells that arise from plant somatic cells.
Meristematic cells are totipotent, meaning they retain the ability to differentiate into any plant cell type. As they divide, they generate new cells, some of which remain meristematic while others differentiate into specialized cells that typically lose the ability to divide or produce new cell types.
Archaeocytes (from Greek archaios "beginning" and kytos "hollow vessel") or amoebocytes are amoeboid cells found in sponges. They are totipotent and have varied functions depending on the species. The structure of these cells match to that of the stem cells as of containing high cytoplasmic content that helps the cells to morph according to ...
