A canine liver fibrosis model to develop a therapy for liver cirrhosis using cultured bone marrow-derived cells.

ABSTRACT: We have been developing a therapy for liver cirrhosis using cultured autologous bone marrow-derived mesenchymal stem cells (BMSCs). Before human clinical trials can be considered, the safety and efficacy of BMSC infusion in medium to large animals must be confirmed; thus, we developed a canine liver fibrosis model. A small amount of bone marrow fluid was aspirated from the canine humerus to assess the characteristics of BMSCs. We implanted a venous catheter in the stomach and a subcutaneous infusion port in the back of the neck of each canine. Repeated injection of CCl4 through the catheter was performed to induce liver cirrhosis. After 10 weeks of CCl4 injection, eight canines were equally divided into two groups: no cell infusion (control group) and autologous BMSC infusion through the p
