Blastocyst is the source of prostaglandins in the implantation site in the rabbit

PL Pakrasi, SK Dey - Prostaglandins, 1982 - Elsevier
The levels of prostaglandins (PGs) were measured by radioimmunoassay in the
interimplantation and the implantation sites as well as in the implantation site without the
blastocyst in the rabbit on day 7 of pregnancy (168h post coitum). The concentrations of PGs
were also determined in the blastocyst (PGF: 101.59+− 4.33 and PGE-A: 29.74+− 3.11
ng/blastocyst, n= 6) and the blastocel fluid (PGF: 253.55+− 39.56 and PGE-A: 83.29+− 6.60
ng/100 ul, n-4) on day 7. The levels of both PGF and PGE-A were significantly higher in the …
