CSF3 and graft versus host disease: The GIAC protocol is an acronym derived from the following elements: the G-CSF (granulocyte colony-stimulating factor) mobilization of the donor; intensified immunosuppression using post-transplant cyclosporine A, mycophenolate mofetil, and short-course methotrexate; ATG included in the conditioning regimen to prevent GvHD and facilitate engraftment; and the combination of BM and peripheral blood graft sources [50].
