The Art of Science
This photo is of gingival epithelial cells, the cells in the lining of the mouth. The cells are infected with the oral bacteria Porphyromonas gingivalis (green).
Actin cytoskeleton (red), the material that maintains a cell's shape and structure, is highly polymerized, a process that facilitiates infection.
This image was taken with an epifluorescence microscope (Zeiss Axioskope)
24 hours after EPI researchers infected healthy gingival epithelial cells.
The nuclei are stained (blue).
