Caenorhabditis elegans germ line: a model for stem cell biology

Dev Dyn. 2007 Dec;236(12):3343-57. doi: 10.1002/dvdy.21335.

Abstract

Like many stem cell systems, the Caenorhabditis elegans germ line contains a self-renewing germ cell population that is maintained by a niche. Although the exact cellular mechanism for self-renewal is not yet known, three recent studies shed considerable light on the cell cycle behavior of germ cells, including a support for significant and plastic renewal potential. This review brings together the results of the three recent cell-based studies, places them in the context of previous work, and discusses future perspectives for the field.
