A mouse macrophage-like cell line (MMC-1) and its biological characteristics--biological characterization

The biological characteristics of mouse macrophage-like cell line (MMC-1) are described. This cell line has been cultured in vitro for more than 20 months. MMC-1 cells are adherent to typical morphology of macrophages, but bigger in size than those of the uncultivated. They are actively phagocytic with abundant Fc receptors. The karyotypes are mostly pantaploidy. This cell line provides a useful tool for the biological and immunological study of macrophage.
