In mammals, such as mouse and human, timely production of the progesterone receptor (PR) in the proper uterine compartments is critical for preparing the uterus for the initiation and maintenance of pregnancy. Developmentally, the expression of GATA2, a member of the six member zinc-finger family of transcription factors, has been shown to be necessary for multiple non-related tissues, such as the hematopoietic system, adipose maturation and the urogential system. We recently identified Gata2 as a potential progesterone target gene in the mouse uterus; however, the expression of the GATA genes in the mouse uterus during pregnancy has not been demonstrated. In the present study, we examined the expression of GATA2 protein during the phases of pregnancy, including early pregnancy where progesterone (P4) signaling is critical in order to facilitate the window of receptivity for embryo implantation and during the decidualization of the uterine stroma, a process of cellular proliferation and differentiation which is necessary for maintenance of the invading embryo until placentation occurs. Here, we report that GATA2 protein is expressed in the uterine luminal and glandular epithelium pre-implantation, spatio-temporally co-localizing with that of the PR. Additionally, GATA2 continues to be expressed in the decidualized stroma throughout early pregnancy indicating a role in the maintenance of decidual cells. Based on these findings, we conclude that GATA2 is expressed during critical phases of early pregnancy, similar to that of the PR, and that it may play a major role in mediating P4 signaling in the mouse uterus.
