Table 1. The percentage of viable MSCs (counted after Tripan Blue staining) after 2, 6, 12, and 18 h of treatment using P. aeruginosa QSSMs.

	Viability during time
Experimental condition	2 h	6 h	12 h	18 h
MSC controla	99%	99%	100%	99%
50 μM OdDHL	81%*	63%*	55%**	37%***
50 μM C4-HSL	99%	99%	93%	90%
50 μM PQS	99%	94%	91%	71%*
50 μM HHQ	99%	99%	93%	86%*

Note: ^aMSC control contain the same amount of HPLC grade MeOH used for test samples. *P < 0.05, **P < 0.01, ***P < 0.001, based on ANOVA and Bonferroni post test of medians of 3 independent experiments performed in triplicate (n = 3).
