Figure 6. Levels of TGF-β in BAL fluid and blood after a single instillation of DEPs (n = 4).

Figure 6

BAL fluid and serum samples were harvested and pooled on days 1, 7, 14, and 28 after DEP instillation, and pooled (500 µL per mouse) to 4 test samples per group for further analysis, respectively. The levels in each group were calculated as mean ± SD of the values measured. *P<0.05; **P<0.01.
