Stratum

  1. The trophoblast differentiates into an actively invading, superficial layer, the syncytiotrophoblast, and a deep stratum, the cytotrophoblast. (Web site)

Layers

  1. The outer layer, or trophoblast, will produce the placenta that nourishes the developing embryo. (Web site)

Embryonic Stem Cells

  1. In contrast to embryonic stem cells, the trophoblast does not come from the inner cell mass, but from cells surrounding it.

Innate Immune System

  1. This previously unknown function indicates that the trophoblast acts as a pregnancy-specific component of the innate immune system.

Allantois

  1. The chorioallantoic placenta is formed of trophoblast and allantois and is vascularized by the allantoic or umbilical vessels. (Web site)

Morula

  1. Cavitation occurrs next, where the outermost layer of cells - the trophoblast - secrete water into the morula.

  3. Cleavage (continue) • Some fluid passes into the morula separates the inner cell mass from the trophoblast. (Web site)

Embryoblast

  2. In summary, the early embryo has two cell types: the trophoblast and the embryoblast. (Web site)
