Detection of Snai1 expression in human lung tissue. The EMT transcription factor was detected by confocal immunofluorescence microscopy. The mean fluorescence intensity of Snai1 in each whole image was automatically quantified by Image-Pro Plus software and expressed in fluorescence units (FU). Bar graph represents the average value from three independent experiments. Increased expression of Snai1 (green) was observed in the lung sections from biopsy (5 d) and autopsy (62 d). P-values were calculated using two-tailed Student’s t-tests. ^#, P < 0.01.
