Expressions of apoptosis-regulating factors in bovine retained placenta.

abstract：BACKGROUND/PURPOSE:Human placenta and chorion are rapidly growing transient embryonic organs built from diverse cell populations that are of either, ectodermal [placenta and chorion specific trophoblast (TB) cells], or mesodermal origin [villous core and chorionic mesenchyme]. The development of placenta and chorion is...
