Fig. 3. Hypoxia decreases the TER of NHNE cells. NHNE cells were incubated under hypoxic conditions for 8 hours, and TER values were measured immediately. The mean TER values of control and hypoxia-conditioned cells were 407.5±43.76 and 199.5±41.17, respectively (n=4, ^*p<0.01). TER, trans-epithelial resistance; NHNE, normal human nasal epithelial.
