Bipotent is a term that refers to the ability of a stem cell to give rise to two different specialized cell types. In the context of stem cell research, there are several synonyms that are frequently used to describe this characteristic, including two-way, dual-potential, and bivalent. Some researchers might also use the term "oligopotent" to indicate that a stem cell is capable of generating a limited number of cell types, whereas others might prefer "multipotent" when referring to cells that can differentiate into multiple specialized cell types. Regardless of which synonym is used, the concept of bipotency is essential to understanding the remarkable versatility and regenerative power of stem cells.
