[Neutrophils do not affect clonal growth of granulocyte progenitor cells cultured in vivo in diffuse chambers].

The effect of polymorphonuclear leukocytes on the growth of granulocytic progenitors in the diffusion chamber culture (CFU-dG) has been studied. It has been shown that peripheral blood neutrophils do not affect the myeloid colony formation in this culture system. The inhibition of CFU-dG growth, observed in the presence of peripheral blood leukocytes was dependent on prostaglandins release from monocytes.
