Among various techniques used for measurement of chimerism in humans, microsatellite DNA profiling has been considered the most versatile one that can discriminate between two individuals. We adopted a commercially available short tandem repeat profiling methodology to cynomolgus monkeys using two human specific alleles, TPOX and CSF1PO. Polymerase chain reaction (PCR) was used to amplify these alleles, and the analysis of the PCR products was performed by capillary electrophoresis. Of 54 cynomolgus macaques investigated, only one pair with the same ABO blood type demonstrated identity at both alleles. This implies that this technique should interfere minimally with the assignment of donor-recipient pairs based upon molecular tissue typing or mixed lymphocyte cultures. | lld:pubmed |
