CXCR4 immunostained sections of the studied groups. A, a (control Group): minimal immune expression for CXCR4 (arrow), the reaction is cytoplasmic (arrowhead). B, b (4wks CCl4 treated group): positive immune reactivity in the portal tract and hepatic lobule (arrows), the reaction is mainly cytoplasmic (arrowheads). C, c (8wks CCl4 treated group): strong positive immune reactivity in the portal tract and scattered all over the hepatic lobule (arrows), the reaction is both cytoplasmic & nuclear (arrowheads). D, d (spontaneous reversion group 2wks): positive immune reactivity in the portal tract and hepatic lobule (arrows), the reaction is both cytoplasmic & nuclear (arrowheads). E, e (spontaneous reversion group 4wks): few positive cells are seen scattered in the portal tract and at the periphery of the hepatic lobules (arrows), the reaction is mainly cytoplasmic (arrowheads)
