BCRP/ABCG2 as Stem Cell Marker (SJ-97-0016)

St. Jude Reference #SJ-97-0016


Breast Cancer Resistance Protein (BCRP), also know as ABCG2, is an ABC transport protein discovered to be a highly specific marker for stem cells. Agents that specifically recognize and/or bind to BCRP are provided, along with methods for using such agents to identify and isolate stem cells. Methods for ex vivo expansion of stem cells modified to express ABC transporters such as BCRP or MDR1 are also provided.
