Generation of Hepatic Organoids with Biliary Structures.

Methods Mol Biol 2019 ;1905:175-185

Institute of Industrial Science, The University of Tokyo, Tokyo, Japan.

Incorporation of bile drainage system into engineered liver tissue is an important issue to advance liver regenerative medicine. Our group reported that three-dimensional (3D) coculture of fetal liver cells (FLCs) and adult rat biliary epithelial cells (BECs) allows reconstruction of hepatic spheroids that possess bile ductular structures. In this chapter, we describe the detailed protocol to isolate FLCs and BECs and to generate the spheroids with bile drainage system using these two types of primary cells. Read More

Inducible pluripotent stem (iPS) cells are multipotent stem cells that are produced by gene transfer of reprogramming factors to somatic cells. They are thought to be an important source of regenerative medicine because of their pluripotency and self-renewal ability. Although the liver has high regeneration ability, continuous death of hepatocytes due to chronic inflammation leads to liver cirrhosis and liver carcinoma. Read More

Isolation and Expansion of Rat Hepatocytic Progenitor Cells.

Methods Mol Biol 2019 ;1905:29-41

Department of Tissue Development and Regeneration, Research Institute for Frontier Medicine, Sapporo Medical University School of Medicine, Sapporo, Japan.

This protocol showed procedures to isolate and expand small hepatocytes (SHs), as hepatocytic progenitor cells, from a rat liver. SHs are identified as a subpopulation of mature hepatocytes in a healthy liver. SHs can proliferate to form colonies in serum-free medium on hyaluronic acid-coated dishes, of which cells show CD44 positivity (CD44 SHs). Read More

A Comparative Study of Single and Dual Perfusion During End-ischemic Subnormothermic Liver Machine Preservation.

Transplant Direct 2018 Nov 23;4(11):e400. Epub 2018 Oct 23.

Division of Organ Transplantation, Department of Surgery, UMass Memorial Medical Center, University of Massachusetts, Worcester, MA.

Background: It remains controversial if arterial perfusion in addition to portal vein perfusion during machine preservation improves liver graft quality. Comparative studies using both techniques are lacking. We studied the impact of using single or dual machine perfusion of donation after circulatory death rat livers. Read More
