    Summary

    A new method allows for easy in vitro culture of mouse lymphocytes. Purified lymphocytes from blood, spleen, and thymus show good PHA stimulation responses, with thymus cells responding the least.

    Area of Science:

    • Immunology
    • Cell Biology
    • Laboratory Methods

    Background:

    • In vitro lymphocyte culture is crucial for immunological studies.
    • Efficient purification of lymphocytes from various mouse tissues is essential for reliable experimental outcomes.

    Purpose of the Study:

    • To describe a simple and reproducible method for in vitro culture of mouse lymphocytes.
    • To evaluate the response of lymphocytes from different mouse sources to in vitro stimulation.

    Main Methods:

    • Lymphocyte isolation using differential centrifugation through Ficoll-Hypaque gradient.
    • In vitro culture of purified lymphocytes.
    • Assessment of lymphocyte activation via blast transformation and tritiated thymidine incorporation following phytohemagglutinin (PHA) stimulation.

    Main Results:

    • The described method successfully cultured mouse lymphocytes from peripheral blood, spleen, and thymus.
    • Lymphocytes from all tested sources exhibited significant responses to PHA stimulation.
    • Thymus-derived lymphocytes showed the lowest response values compared to peripheral blood and spleen lymphocytes.

    Conclusions:

    • The Ficoll-Hypaque gradient method provides a reliable means for purifying mouse lymphocytes for in vitro culture.
    • PHA stimulation effectively activates lymphocytes from various mouse tissues, though with differential responsiveness.
    • This method facilitates further research into lymphocyte function and activation.
