Fluorescent in situ hybridization on flow-sorted cells as a tool for evaluating minimal residual disease or chimerism after allogenic bone marrow transplantation.


We studied the feasibility and the sensitivity of fluorescent in situ hybridization (FISH) using leukemic or host/donor-specific probes on flow-sorted cells to assess minimal residual disease (MRD) or chimerism in transplanted patients in complete remission. We first performed experimental models of MRD and chimerism by mixing HL60 cells and normal… (More)
