FGF-10 expression in the lung of hyperoxia group and air group. At different time points, the lung was collected for the detection of mRNA and protein expression of FGF-10 by RT-PCR and Western blotting after extraction of total RNA. Results showed, on day 4, 7 and 14, FGF-10 expression was comparable between two groups; on day 21, the FGF-10 mRNA expression in hyperoxia group reduced significantly when compared with air group (*P<0.05). Western blotting showed FGF-10 expression in the lung of hyperoxia group decreased over time.
