Abstract

This study analyzed the gene expression and protein content of Cripto 1 (Cr1) at the maternal-placental interface during gestation, through RT-PCR and Western Blotting. Our results showed that the protein Cr1 is present during placental development in both compartments of the maternal-placental interface. The content gradually increased at the fetal compartment, decreased at the decidua after day 13.5 of gestation, but nevertheless, as high values in comparison with those at the fetal compartment. The semi-quantitative evaluations of Cr1 through PCR indicated low expression at the post-implantation and final gestational periods in both compartments, showing a significant increase on day 10.5 and mainly 13.5 of gestation (p<0,05). The presence of Cr1 at the maternal-placental interface indicates a relevant role played by this factor, possibly during placental development or, yet, in the processes developed in this particular site and that are essential for gestational maintenance and success.
