Axin2+ endometrial stem cells: the source of endometrial regeneration and cancer

Abstract

Menstruation is one of the basic but poorly understood life processes in primates during which females shed inner uterine lining every month only to be completely regenerated back within a week. The definitive evidence for the existence and/or identity of stem cells responsible for this process has remained elusive for more than six decades now. Recently, we reported Axin2, a classical Wnt reporter gene, as a marker for endometrial stem cells that also serve as the cells of origin for endometrial cancer.
