title: Properties of extra-embryonic ectoderm isolated from postimplantation mouse embryos.
abstract: Extra-embryonic ectoderm isolated from the mouse embryo as late as 81/2 days post coitum can form cells with the morphological characteristics of trophoblast giant cells both in ectopic sites and in vitro. This similarity to the properties of ectoplacental cone tissue provides further support for the postulated common origin of both tissues from the trophectoderm of the blastocyst.
