Sorrel Extract Reduces Oxidant Production in Airway Epithelial Cells Exposed to Swine Barn Dust Extract In Vitro

Figure 2

Effect of DE exposure on LDH release, cell proliferation, and viability of NHBE cells. (a) LDH activity within supernatant after 6-hour exposure to 1-8% DE, . (b) Cell proliferation (BrdU assay) after 24-hour exposure to 1-8% DE, . (c) Representative images of LIVE/DEAD staining to assess cell viability after exposure to 5% DE for 7 hours, . The green fluorescence (i.e., GFP) and red fluorescence (i.e., RFP), respectively, represent live cells stained with calcein and dead cells stained with ethidium homodimer. Data are presented as the for (a) and (b).
