FXRα a new actor of germinal stem cells fate.
The FXRα nuclear receptor (Farnesoid-X-Receptor alpha) is a key factor controlling the male sex hormone synthesis within the testis. However, its roles in male germ cell homeostasis have not yet been studied. Using a phenotyping approach of Fxra deficient mice, the team of David Volle has characterized unexpected roles of FXRa with germ cell lineage. There, FXRa is involved in the establishment and the maintenance of undifferentiated germ cell pool and in turn, influences male fertility during aging.
