Abstract: | A study was performed in order to investigate the participation of prostaglandins (PGs) during implantation. The effects of indomethacin on mouse blastocyst attachment and trophoblastic outgrowth were examined in vitro. Studies were also carried out on cultures supplemented with PGE2 and/or PGF2 alpha along with indomethacin. (1) Blastocyst attachment and trophoblastic outgrowth were inhibited by indomethacin dose-dependency. (2) In the cultures supplemented with indomethacin and PGE2 or PGF2 alpha, respectively, the inhibitory effects of indomethacin were reduced. (3) In the cultures supplemented with all three substances with treatment (1) and (2), inhibition of indomethacin was partially reversed, but still lower than control group without indomethacin. The above results indicate that both PGE2 and PGF2 alpha have a promoting effect on implantation, and PGF2 alpha was more effective than PGE2. |
