Figure 1 Schema of study design. Patients were mobilized with granulocyte-macrophage colony-stimulating factor (GM-CSF) and cyclophosphamide. Peripheral blood mononuclear cells (PBMC) were collected and CD34+Thy1+cells selected using a two-step process. For safety concerns with this new source of cells, the first cohort of patient recieved melphalan alone as conditioning regimen followed by CD34+Thy1+ infusion. Subsequent patient cohorts received melphalan + total body irradiation (TBI) and decreasing numbers of CD34+Thy1+ cells. Progression from cohort 1 to 4 was based on the demonstration of sustained engraftment and adequate safety in the current cohort. The fifth cohort was added after considering poor engraftment results with the low CD34+Thy1+ cell dose cohorts. All patients received G-CSF after transplant and were followed-up 1 year after transplant Experimental Hematology 2000 28, 858-870DOI: (10.1016/S0301-472X(00)00169-7)
