TJ between EC and between EC and MDM. TEM images showing untreated cells in the triple cell co-culture model in A. The tight junctions (TJ) the adherens junctions (AJ), as well as the desomosomes (D) between two neighbouring EC are shown in the detailed view in A1. TJ-like structures (white arrows, B1 and B2) between a MDM and two neighbouring EC in the triple cell co-culture model is shown in overview in B. B1 and B2 are detailed views. The morphology and as well as the internalized gold NP (black arrow in B2) prove that the described cell is a MDM.
