Figure 2From: Newborn pig trachea cell line cultured in air-liquid interface conditions allows a partial in vitro representation of the porcine upper airway tissueMeasurement of transepithelial electrical resistance (TEER) in NPTr cells cultured in ALI conditions. Cells were cultured for a maximum of twenty-two days using different media (A, B, and C). Data are representative of two independent experiments and are presented as means +/− SEM, (n = 6).Back to article page
