(CFU) (kol'ŏ-nē-fōrm'ing yū'nit)
1. A stem cell in culture capable of proliferating and differentiating into more mature cells. If the CFU is committed to a specific cell line, it is designated by an additional letter to indicate its commitment; e.g., CFU-E is committed to erythroid maturation; CFU-GM is committed to granulocyte-monocyte maturation.
2. Term used in microbiology to designate a colony formed from a single bacterium or fungus.
