<P> In biology, oligopotency is the ability of progenitor cells to differentiate into a few cell types . It is a degree of potency . Examples of oligopotent stem cells are the lymphoid or myeloid stem cells . A lymphoid cell specifically, can give rise to various blood cells such as B and T cells, however, not to a different blood cell type like a red blood cell . Examples of progenitor cells are vascular stem cells that have the capacity to become both endothelial or smooth muscle cells . </P> <P> In cell biology, a unipotent cell is the concept that one stem cell has the capacity to differentiate into only one cell type . It is currently unclear if true unipotent stem cells exist . Hepatoblasts, which differentiate into hepatocytes (which constitute most of the liver) or cholangiocytes (epithelial cells of the bile duct), are bipotent . A close synonym for unipotent cell is precursor cell . </P>

What are the differences between totipotent pluripotent and multipotent stem cells
