Viability of hPDLSCs and hGMSCs in response to stimulation with different LPS preparations. Primary hPDLSCs and hGMSCs were stimulated with commercially available “standard” P. gingivalis LPS (1 μg/ml), “ultrapure” P. gingivalis LPS (1 μg/ml), and “ultrapure” E. coli LPS (1 μg/ml) in the presence of 250 ng/ml sCD14 for 24 hours. Cell viability was assessed by the MTT method. The y-axis shows OD values (570 nm) presented as mean ± s.e.m. of five different donors. ∗Significantly different vs. control.
