Figure 5From: Intracellular survival and vascular cell-to-cell transmission of Porphyromonas gingivalisP. gingivalis can be localized in newly added host cells. (A) 24 hour co-culture of primary invaded endothelial cell (iEC) with freshly added SMC. The arrow identifies the presence of P. gingivalis in SMC. (B) The confocal microscope image (depth of 1.57 μm) identifying P. gingivalis internalized by a smooth muscle cell after co-culturing with invaded endothelial cells.Back to article page
