    ..Additionally, the similar profiles of endometrial HOXA10 and PGHS-2 expression in the presence of E(2) and P(4) indicate that both genes are simultaneously regulated by steroids in the porcine uterus. ..

    ..Moreover, the co-culture system of LE and ST cells is a promising model for the study of endometrial response to conceptus-derived factors. ..

    ..In summary, LIF and IL-6 are important components of embryo-uterine interactions during early pregnancy in the pig, and may contribute to successful conceptus implantation. ..

    ..In summary, PTGIR is expressed in porcine conceptuses, and PGI2 acting through this receptor may promote the attachment and proliferation of Tr cells, thereby facilitating conceptus implantation. ..
