Figure 1From: Hypoxia down-regulates expression of secretory leukocyte protease inhibitor in bronchial epithelial cells via TGF-β1Hypoxia reduces SLPI expression in differentiated bronchial epithelial cells. SLPI concentrations in the cell medium (A) and rinsing fluid (B) from air liquid interface cultures incubated at 21% or 1% O2. The figure shows means and SEM for at least 3 independent experiments.Back to article page
