What can cause low white blood cells?

A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Autoimmune disorders that destroy white blood cells or bone marrow cells.

What stimulates the production of white blood cells?

Different growth factors stimulate the blood stem cells in the bone marrow to produce different types of blood cells. For example, granulocyte-colony stimulating factor (G-CSF) stimulates the production of white cells called neutrophils while erythropoeitin (EPO) stimulates the production of red cells.
