Selective Repopulation of Mice Liver after Fas-Resistant Hepatocyte Transplantation

Therapeutic liver repopulation in a mouse model of hypercholesterolemia.

Liver repopulation constitutes an attractive approach for the treatment of liver disorders or of diseases requiring abundant secretion of an active protein. We have described previously a model of selective repopulation of a normal liver by Fas/CD95-resistant hepatocytes, in which we achieved up to 16% hepatocyte repopulation. In the present study, we investigated the therapeutic efficacy of th...

Cell transplantation after oxidative hepatic preconditioning with radiation and ischemia-reperfusion leads to extensive liver repopulation.

The inability of transplanted cells to proliferate in the normal liver hampers cell therapy. We considered that oxidative hepatic DNA damage would impair the survival of native cells and promote proliferation in transplanted cells. Dipeptidyl peptidase-deficient F344 rats were preconditioned with whole liver radiation and warm ischemia-reperfusion followed by intrasplenic transplantation of syn...

Hepatocyte Transplantation: Cell Sheet Technology for Liver Cell Transplantation

PURPOSE OF REVIEW We will review the recent developments of cell sheet technology as a feasible tissue engineering approach. Specifically, we will focus on the technological advancement for engineering functional liver tissue using cell sheet technology, and the associated therapeutic effect of cell sheets for liver diseases, highlighting hemophilia. RECENT FINDINGS Cell-based therapies using...

Liver Biopsy After Liver Transplantation

Liver regeneration after liver transplantation.

BACKGROUND/PURPOSE The liver has a remarkable capacity to regenerate after injury or resection. The aim of this review is to outline the mechanisms and factors affecting liver regeneration after liver transplantation. METHODS Relevant studies were reviewed using Medline, PubMed and Springer databases. RESULTS A variety of cytokines (such as interleukin-6 and tumor necrosis factor-α), growth...
