Abstract:
The effects on bone marrow cellularity and morphology of 6 days' treatment with granulocyte colony-stimulating factor (G-CSF) in 35 patients were studied. Examination of trephine biopsies showed a highly significant increase in cellularity (P < 10-13). Assessment of aspirates revealed an increase in the myeloid to erythroid (M : E) ratio (P = 0.00006), the proportion of myeloid cells (P < 10-8), myelocytes (P = 0.00007), metamyelocytes (P = 0.04), band forms (P = 0.0005) and neutrophils (P = 0.02). This study presents a comprehensive analysis of the effects of six days' administration of G-CSF on human bone marrow.
