Figure 2From: The periodontal pathogen Porphyromonas gingivalis changes the gene expression in vascular smooth muscle cells involving the TGFbeta/Notch signalling pathway and increased cell proliferationP. gingivalis increases AoSMCs proliferation. The neutral red assay was used to analyze changes in AoSMCs growth after challenge with P. gingivalis at the concentration of 10MOI for 24 h in the absence or presence of viable P. gingivalis. The results are presented as the mean ± SEM of four separate experiments. *, p < 0.05. **, p < 0.005. n = 4.Back to article page
