    This study presents a simple method to obtain chicken peritoneal exudate cells for research. These cells, when cultured, demonstrate high phagocytic activity and sustained function in vitro.

    Area of Science:

    • Immunology
    • Cell Biology
    • Avian Biology

    Background:

    • Peritoneal exudate cells (PECs) are crucial for studying cellular immunity.
    • Efficient methods for isolating and culturing functional PECs are essential for immunological research.

    Purpose of the Study:

    • To develop a straightforward and rapid technique for inducing and harvesting peritoneal exudate cells from chickens.
    • To evaluate the phagocytic capacity and in vitro stability of these isolated chicken PECs.

    Main Methods:

    • Intraperitoneal injection of 3% washed Sephadex particles suspension into 5-6 week old chickens.
    • Harvesting, washing, and suspension of peritoneal exudate cells in Hank's solution.
    • Culture of cells on 4-chamber slides to form adherent monolayers and assessment of phagocytosis using latex particles or antibody-sensitized sheep erythrocytes.

    Main Results:

    • A high yield of peritoneal exudate cells was obtained within 3-4 days post-injection.
    • Adherent monolayers exhibited near-complete phagocytic activity (99.5-100%) against latex particles and/or sensitized erythrocytes.
    • Phagocytic capacity remained stable during several weeks of in vitro cultivation.

    Conclusions:

    • The described Sephadex particle injection method is an effective technique for generating functional chicken peritoneal exudate cells.
    • Chicken PEC monolayers are a robust model for studying phagocytosis and cellular immune responses in vitro.
    • This method provides a valuable tool for avian immunology research, offering sustained phagocytic activity in cultured cells.
