Cancer Research Centre AbstractA chimerism analysis for monitoring donor DNA engraftment in allogeneic peripheral blood stem cell transplantation (PBSCT) in a patient with acute lymphoblastic leukaemia (ALL) at day 14 (D14) and day 28 (D28) of post-PBSCT was performed. Five specific sequence polymorphisms located in five different chromosomes were selected for this study. Only one marker (S02) was able to discriminate DNA profiles between the donor and the recipient. This particular marker was negative in the recipient but positive in the donor. By using 15 serial-halved dilutions of mixed DNAs using TaqMan technology, a linear correlation (r2) of 0.97 was obtained. In the post-PBSCT analysis, we managed to detect presence of the donor DNA profile at D14, which was slightly reduced at D28. The Ct values were 27.01 at D14 and 29.38 at D28. The percentage of donor DNA detected in the recipient’s DNA decreased from 37.18% at D14 to 30.68% at D28. Repository Staff Only: item control page
