Table 1. Percentage of viable H9 cells.

Percentages of cell viability and density were measured and calculated after 24 hours for six flasks of H9 cells: three with 0% CSEM for 24 hours and three with 50% CSEM. CSEM, cigarette smoke extract media.

% CSEM	Viable cells/mL	% Viability
0% - flask #1	1,195,679	98.1
0% - flask #2	1,196,918	97.1
0% - flask #3	1,248,749	96.7
50% - flask #1	723,372.7	85.9
50% - flask #2	632,603.8	86.1
50% - flask #3	715,714.1	87.9
