Lacrimal gland MEC were either left untreated (control) of incubated
with IL-1β (10 ng/ml) for 2, 4, or 7 days. Three or 4 random images were
taken, using the same camera setting for all conditions, from each well and GFP
intensity was quantified using ImageJ/Fiji software, as described in the Methods
section. (A) Shows representative images from control and treated
MEC at all time points measured and (B) Shows averaged data from 4
independent experiments. Compared to the control group, IL-1β treatment
significantly decreased GFP intensity at all time points measured (Mann-Whitney
U test). Data are means ± SD; n=20-23 for day 0; n=32 for day 2; n=31-32
for day 4; and n=28 for day 7 with all data from 4 independent experiments.
Scale bar = 50 μm.
