A direct comparison of immunological characteristics of granulocyte colony-stimulating factor (G-CSF)-primed bone marrow grafts and G-CSF-mobilized peripheral blood grafts.

Our preliminary results suggest the existence of quantitative and qualitative differences in immune cells and type1 and type2 cytokines between granulocyte colony-stimulating factor (G-CSF) primed bone marrow (G-BM) and G-CSF-mobilized peripheral blood grafts (G-PB). Our findings suggest that lower T-cell hyporesponsiveness and easier polarization of T cells from Th1 to Th2 are found in G-BM.
