Control of binucleate cell migration in the placenta of sheep and goats

摘要

Summary. In the ruminant placenta 15–20% of the trophectodermal epithelium consists of granulated binucleate cells (BNC). In the sheep the granules contain ovine placental lactogen (oPL). These cells migrate from the trophectoderm to form fetomaternal hybrid tissue from implantation to term.
