TfR1- and ED-1-positive cells in serial sections of rat liver tissue at various time points after turpentine oil (TO) administration (DAP1 DAPI nuclear staining [blue]). a Control TfR1. b TfR1 at 6 h after TO treatment. c Control ED-1. d ED-1 at 6 h after TO injection. Insets Higher magnification of boxed areas in a, b showing TfR1-positive cells in liver tissue. Results are representative of three animals. Original magnification: ×100. Bar 100 μm
