Abstract:
Objective To study the validation of fluorescent multiplex microsatellite amplification technique for use in the caseworks of umbilical blood cell transplantation monitor. Methods Six post-transplant recipients of umbilical cord blood cell transplantation were monitored by analyzing microsatellite DNA loci. DNA samples were amplified using a fluorescent labeling primers multiplex amplification system of 15 microsatellites markers, followed by typing on a DNA automated sequencer. Recipients' or donors' microsatellites DNA profiles were compared before and after transplantation. Results All recipients and donors exhibited different DNA profiles. Without reference samples of pre-transplant or donors, the changes of the 15 microsetellites genotypes of the post-transplant recipients still could be analyzed. The recipient type turned to donor type was observed over time. Conclusion Under the condition of using multiplex amplification of the 15 microsatellites to monitor the umbilical blood cell transplantation, reference sample of pre-transplant or donor did not need to be detected simultaneously.
