PG - 452-60 LID - S1934-5909(12)00546-2 [pii] LID - 10.1016/j.stem.2012.09.009 [doi] AB - Decades ago, two nonoverlapping crypt stem cell populations were proposed: Leblond's Crypt Base Columnar (CBC) cell and Potten's +4 cell. The identification of CBC markers including Lgr5 has confirmed Leblond's predictions that CBC cells are anatomically distinct, long-lived stem cells that permanently cycle. While Potten originally described +4 cells as proliferative and unusually radiation-sensitive, recent efforts to identify +4 stem cells have focused on the identification of cells that are quiescent and radiation-resistant. Here, we describe commonalities and discrepancies between the individual studies and discuss challenges of marker-based lineage tracing. CI - Copyright (c) 2012 Elsevier Inc. All rights reserved.
