Limiting dilution analysis of granulocyte-macrophage progenitor cells was performed by using adherent and T cell-depleted normal human bone marrow and the recombinant human growth factors, granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF). Estimated frequencies for progenitor cells responding to G-CSF were one in 489 for colonies scored ...

Granulocyte colony-stimulating factor was discovered during attempts to define the normal regulators present in cell supernatants that could induce terminal differentiation of the murine myeloid leukemic cell line WEHI-3B D+. The purification and subsequent cloning of both murine and human G-CSF allowed the normal functions of this molecule to be elucidated and indicated that it was a relativel...

conclusions the present study showed that g-csf is not superior to placebo in production of protective antibody titers after hbv vaccination but could result in a more rapid antibody response, compared to the placebo. results there was no statistically significant difference between anti-hbv antibody titers in patients receiving double dose hbv vaccination plus g-csf and patients receiving doub...
