In addition, all included subjects underwent the same procedures of donor priming (recombinant human granulocyte-colony stimulating factor), graft harvesting (peripheral blood progenitor cells and unmanipulated bone marrow), and GVHD prophylaxis (cyclosporine A and short-term methotrexate with mycophenolate mofetil). The gene discussed is CSF3; the disease is graft versus host disease.
