Immune Cell Isolation from Mouse Femur Bone Marrow.

The bone marrow is the site of hematopoesis and contains mixed population of blood cells including erythrocytes, granulocytes, monocytes, dendritic cells, lymphocytes and hematopoietic stem cells. The following protocol provides a simple and fast method for isolation of bone marrow immune cells (no erythrocytes) from mouse femurs with a yield of approximate 8 × 10(7) cells in 5 ml culture media (1.6 × 10(4) cells/μl). Further isolation or flow cytometric analysis might be required for study of specific immune cell types.
