Erythrocytes, platelets and granulocytes (neutrophils, eosinophils and basophils) are derived from pluripotential stem cells. These give rise to multipotential colony-forming unit progenitors for granulocytes, erythrocytes, monocytes/macrophages and megakaryocytes. Under the influence of interleukins and colony-stimulating factors, committed stem cells develop into differentiated blood cells (erythrocytes, neutrophils, eosinophils, basophils, monocytes and platelets). Neutrophils and monocytes develop from the same colony-forming unit. Although the bone marrow produces some lymphocytes most are derived from the peripheral lymphoid tissue.

The bone marrow also contains a reserve of mature cells, which can be released into the circulation. Thus, changes in the blood are affected by the reserve capacity of the bone marrow and the life span of cells in the circulation (canine erythrocytes 120 days, platelets 10 days, granulocytes 8 hours).
