Hypoblast cell

Hypoblast cell

Low power TEM of a hypoblast cell of a stage 3 embryo in vitro, 145-170 hours post-insemination (original magnification x5,000). Extruded material (asterisk) is in the extracellular space and appears to form a basement membrane-like structure lining the epiblast cells.

BC = blastocystic cavity (blastocoele)
BM = basement membrane
E = epiblast cell
