If a stem cell divides symmetrically, have the ability to produce either two stem cells (increasing the stem cell pool by one) or two committed cells (decreasing the pool by one). This is called symmetrical renewing or symmetrical differentiating.

If a stem cell divides asymmetrically, produce two types of cells (a stem cell & a developmentally committed cell) are produced at each division, is called the single stem cell asymmetry.

Cell potency is a cell’s ability to differentiate into other cell types. Stem cell has the power, or potency, to produce many different types of differentiated cells.

The potency of a cell is an intrinsic property and is greater than or equal to its fate. Potency is described as the gene activation potential within a cell which begins with – 

Totipotency, Pluripotency, Multipotency  and finally Unipotency.

Totipotency

the ability of a single cell to divide and produce all of the differentiated cells in an organism (embryonic and extra embryonic cells).
