Overview of currently used bone marrow- and/or peripheral blood-derived “EPC” names and characterizations as well as culture conditions. Circulating EPC can be identified markers such as CD133, VEGFR, and CD34. EPCs in culture can be divided into early outgrowth EPC, colony forming units (Hill-colonies), circulating angiogenic cells (CAC), and late outgrowth EPC (modified from Ref. 89).
