title: Distinct effect of G-CSF on the growth and differentiation of myeloid progenitor cells from chronic idiopathic neutropenia.
abstract: Chronic idiopathic neutropenia (CIN) is a disorder characterized by severe neutropenia and a maturational arrest of the neutrophil precursors in the bone marrow. We examined the effect of recombinant human granulocyte-colony stimulating factor (rhG-CSF) on the growth and maturation of the myeloid progenitor cells from a patient with CIN. The patient's marrow cells showed poor colony forming activity, but a normal differentiating capacity to the stimulation with rhG-CSF, although they displayed a normal colony forming capacity in the presence of GM-CSF. Our observation indicates the distinct effect of rhG-CSF on the growth and maturation of the myeloid progenitors from a CIN patient.
