Background/Aim: We have designed an experimental model in which transplantation of normal hepatocytes into rats previously treated with retrorsine (a naturally-occurring pyrrolizidine alkaloid) results in near-complete replacement of the recipient liver by donor-derived cells. Two/thirds partial hepatectomy was found to be essential for this process to occur. To probe this finding, in the present...
Background/Aims: We have recently developed a new model of extensive liver repopulation by transplanted hepatocytes following exposure to pyrrolizidine alkaloids. In the present study, the effect of 2/3 partial hepatectomy (PH) and that of a potent direct liver mitogen, lead nitrate, were compared in their ability to modulate the kinetics of liver repopulation.Methods: Fischer 344 rats deficient in...
