Liver tissues stored in 10% neutral buffered formalin were dehydrated using a Leica
tissue processor (Leica, Australia). The dehydrated samples were embedded in paraffin and cut into 4-μm-thick sections. Mayer’s hematoxylin and eosin (H&E) staining was
performed and images were taken from Olympus BX41 microscope with a 20× objective
lens using an Olympus DP72 digital camera (Olympus, Australia).
