Preparation and Culture of Human Liver Resident Immune Cells.

Co-cultivation of tumor cells and liver resident immune cells or other non-parenchymal cells (NPCs) from the same donor is important for the study of cancer metastasis. So far, little is known about the mechanism of tumor cell or pathogen clearance, leukocyte infiltration, and immune cell recruitment in the human liver. To investigate these processes in vitro, the use of primary human hepatocytes and non-parenchymal cell, especially immune cell, co-culture systems play essential roles in the establishment of cell-cell and cell-extracellular matrix communications similar to native liver tissues. Hepatic non-parenchymal cells mainly comprise liver sinusoid endothelial cells (LSECs), microvascular endothelial cells, hepatic stellate cells, Kupffer cells (KCs), natural killer T (iNKT) cells, and dendritic cells (DCs). Here we describe procedures for preparation, isolation, and culture of human liver resident immune cells and other non-parenchymal cells. © 2018 by John Wiley & Sons, Inc.
