Figure 2. P. gingivalis negligibly induces proMMP9 production and cell invasion of Ca9-22 cells.

Figure 2

(A) Low invasive Ca9-22 cells were incubated with P. gingivalis at an MOI of 1 for the indicated times. Culture supernatant samples were collected and analyzed for proMMP9 activation using gelatin zymography. (B) Ca9-22 cell invasion through matrigel-coated transwell membranes at 24 hours after P. gingivalis stimulation. Data are shown as the mean ± SD of three independent experiments and were analyzed with a t test.
