Abstract:
Objective To establish a method for detecting chimerism after allogeneic stem cell transplantation using microsatellite polymorphism. Methods DNA was extracted from bone marrow or peripheral blood of 10 recipients and their donors, DNA fragments including 5 microsatellite loci were amplified by PCR, the polymorphism of PCR products was analyzed by PAGE and sliver staining, and the quantitative analysis of chimerism was performed using image analysis software. Results [WTBZ]The five selected STR loci had high polymorphism, and were suitable for detecting chimerism. The sensitivity of sliver staining was 90%. Conclusion Microsatellite polymorphism analysis based on PCR is a sensitive and accurate method to detecting chimerism after allogeneic stem cell transplantation, but the sensitivity of sliver staining was not so good,so more sensitive methods should be used.
