Stem cell and endometriosis: new knowledge may be producing novel therapies.

Yang J¹, Huang F¹.

Abstract

The human endometrium is a dynamic tissue, which undergoes cycles of growth and regression with each menstrual cycle. Adult progenitor stem cells are likely responsible for this remarkable regenerative capacity; these same progenitor stem cells may also have an enhanced capacity to generate endometriosis if shed in a retrograde fashion. The progenitor stem cells reside in the uterus, and, however, may also travel from other tissues such as bone marrow to repopulate the progenitor population. Mesenchymal stem cells are also involved in the pathogenesis of endometriosis and may be the principle source of endometriosis outside of the peritoneal cavity when they differentiate into endometriosis in ectopic locations. The present short review mainly summarizes the latest observations contributing to the current knowledge regarding the presence and the potential contribution of stem cells in the etiology of endometriosis. All these data can have clinical implications and provide a basis for new potential therapeutic applications.
