Abstract:
Objective:To investigate the effects of sensitized sera on bone marrow transplantation and clarify the role of antibody in the process of rejection.Methods:Two hundred microlitres sensitized sera or non-sensitized sera were injected into normal BALB/c one day before transplantation.Ten millions (1?107) bone marrow cells from C57BL/6 were transfused to the recipients after lethal irradiation.The donor-reactive antibodies in recipients before transplantation were measured by complement-dependent cytotoxicity (CDC) method.Moreover,the survival analysis and engraftment evaluation of the recipients were carried post transplantation.Results:The CDC results showed that donor-reactive antibodies existed in the recipients which had received sensitized sera transfusion.Eighty percent (80%) of the recipients received sensitized sera transfusion died of bone marrow failure about 10 days post transplantation,while the recipients received non-sensitized sera transfusion were long-term alive.Furthermore,the hematopoietic recovery and percentage of donor chimera analysis declined along with time in the sensitized sera transfusion recipients,and there were significant differences compared with those in the non-sensitized sera transfusion recipients (P
