GPC3 and neoplasm: Interestingly, the expression of stem cell markers Dlk1, Epcam and Gpc3 were inter-tumor heterogeneous, being more highly expressed in NEJ634 and NEJ723 tumors in comparison with NEJ687 and NEJ146 tumors, in contrast to the expression profiles of Cyp2e1 and Glul. These data indicate that NEJ634 and NEJ723 tumors are less differentiated.
