PTL attenuates the BLM-induced expression of EMT-related protein. a Representative immunohistochemical staining of lung sections showing E-cadherin, vimentin, MMP1, α-SMA and Col-1 staining. b Expression levels of makers were evaluated by index of immunohistochemical staining. The number of positively stained cells in each group was calculated from twenty different 400× magnified fields under a microscope. The data represent the mean ± standard deviation (SD), n = 10 per group. *, P < 0.05, **P < 0.01 vs. model group
