Schematic of trophoblast cell junctions

Close-up view of a stage 3 embryo in vitro showing a schematic of trophoblast cell junctions. Extremely close connections called tight junctions are formed between the membranes of trophoblastic cells. Disk-shaped junctions called desmosomes also form between trophoblast cell membranes.
