Figure 4. TNF-α cytokine production of mesothelial cells seeded at low density.

Cells were treated with the MK2-inhibitor peptide on polyacrylamide gels of different stiffness compared to tissue culture plastic. Cells were seeded at 21,000 cells/cm². Data is presented as mean ± standard deviation. Asterisks indicate statistically significant difference from IL-1β stimulated control within each substrate group (p<0.05; one-way ANOVA+Tukey post-hoc test).
