Developmental Biology Isolation and Enrichment of Liver Progenitor Subsets Identified by a Novel Surface Marker Combination Henrike Julich-Haertel1, Marina Tiwari1, Christina Mehrfeld1, Elmar Krause2, Miroslaw Kornek1, Veronika Lukacs-Kornek1 1Department of Medicine II, Saarland University Medical Center, 2Department of Physiology, Center for Integrative Physiology and Molecular Medicine (CIPMM), University of Saarland Liver injuries are accompanied by progenitor cell expansion that represents a heterogeneous cell population. Novel classification of this cellular compartment allows for the distinguishing of multiple subsets. The method described here illustrates the flow cytometry analysis and high purity isolation of various subsets that can be used for further assays.
