Objective 　To explore a simple, effective and stable method for the isolation and purification of Kupffer cells from rat liver, enabling further study on the structure and function of these cells in vitro.
Methods 　After laparotomy, a catheter was inserted into the portal vein and secured with artery clamp. Then, the rat liver was perfused and digested with solution Ⅰ and solution Ⅱ containing 0.05% collagenase Ⅳ respectively. The cell suspension was centrifuged with isopycnic sedimentation in a two-step Percoll gradient to harvest Kupffer cells. The isolated Kupffer cells were purified by selective adherence after 30 min of cultivation, and identified by evaluation of phagocytosis of India ink and peroxidase staining with DAB through light and electron microscopy.
Results 　It was verified that the viability of isolated Kupfffer cells was more than 90% through Trypan blue staining. Those Kupffer cells could attach to plastic quickly and phagocytose ink, and had the appearance of “fried eggs” in positive peroxidase staining with a purity of 95%. Under the light microscopy, the appearance of newly isolated Kupffer cells was round with uniform shape and size. After two days of culture, Kupffer cells appeared to distend with irregular or stellate shape. The typical features were observed in the transmission electron micrographs. There were numerous pseudopods and occasional cup-like indentations in the cell membrane of Kupffer cells. The cytoplasm contained numerous types of lysosomes and other phagocytotic vesicles.
Conclusion 　The method for isolating and culturing Kupffer cells in this study is effective and stable, and the biological characters are preserved in the cultured cells.
