We measured the granulocyte-colony stimulating factor (G-CSF) levels in cord blood and peripheral blood obtained from full-term or pre-term infants during the first 3 days of birth. The mean G-CSF level among cord blood (17.2 pg/mL) was similar to that of peripheral blood on day 0 (18.3 pg/mL) and day 1 (13.6 pg/mL), while that of peripheral blood on day 0 was significantly higher than on day 2 (10.9 pg/mL) and day 3 (8.8 pg/mL; both P < 0.05). There was no correlation between neutrophil counts and G-CSF levels. No difference was found in neutrophil counts or G-CSF levels between infants who weighed more or less than 2500 g at birth. These results suggest that the neonatal neutrophil count depends on regulatory factors other than G-CSF.

D016179 Granulocyte Colony-Stimulating Factor A glycoprotein of MW 25 kDa containing internal disulfide bonds. It induces the survival, proliferation, and differentiation of neutrophilic granulocyte precursor cells and functionally activates mature blood neutrophils. Among the family of colony-stimulating factors, G-CSF is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines.
