Table 1.

Comparison of the three potencies of stem cells (totipotent, pluripotent, and multipotent) (Refs. ²⁸, ²⁹).

Potency	Description	Examples
Totipotent	Each cell is able to develop into any cell types.	Cells from early (1–3 days) embryos
Pluripotent	Cells can form most of the cell types except placental tissues.	Some cells of blastocyst (5–14 days)
Multipotent	Cells differentiated, but can make a range of other particular tissues.	Fetal tissue, cord blood, and adult stem cells
