RESUMO

The goal of this study was to characterize Mif expression by trophoblast (TC),fetal placenta (FP) and decidua (D) during mouse pregnancy.Mif was immunolocalized at TC and D on gestation days (gd) 7.5, 10.5, 13.5 and 17.5.Ectoplacental cones (EC) and FP were used for Western blotting and qPCR.D were also used for qRT-PCR.On gd 7.5,DC and TC giant (TGC) showed strong reactivity.On gds 10.517.5,were concentrated in TGC and spongiotrophoblast cells. D reactivity was weaker than 7.5 gd.Protein expression at FP increased from gd 7.5 to 10.5 (p=0.005) and to 13.5 (p=0.03).Higher mRNA expression was found on gd 10.5 and was different from gds 13.5 (p=0.048) and 17.5 (p=0.009).At D on gd 7.5 was greater than those on gds 10.5 (0,012) and 13.5 (0,032).The up-regulation of Mif coincides with the stage that placenta assumes its four-layered organization and the fetal blood circulation begins,This temporal tissue-specific distribution and expression data suggests that Mif may play a modulator role in the onset of placentation or in it adaptation to the uterine environment
