Figure 4. Loss of TSG-6 in skin upregulates the expression of the pro-inflammatory cytokine TNFα.
(a), Western analysis of unwounded skin (upper panel) and of 7-day healing wounds (lower panel), show higher TNFα protein expression in TSG-6 null mice as compared to WT mice. (b), Quantification of multiple Western blot experiments reveals significantly higher expression of TNFα in TSG-6 null skin, both before wounding and in the first 7 days after wounding; mean ± SEM; significance levels are indicated by P-values above the bars (Mann-Whitney Rank Sum test after Shapiro-Wilk tests for normality).
