Abstract

CNmerism, the occurrence of donor Is In long term sold organ recipients has been associated wttbothaoaptanceandreMontfthalrtranspleiMofgans. Our center has isolated bone marrow tram the same cadMrtc kidney donor and Mused SrtOJ per kg on day five and day eleven post amp Malorow UFK50 filinim Kiouppi slwlheiapy, in an attempt to induce a state of tolerance. To test for chimerism Mac crest Bone Marrow Aspirates (BMA) and Peripheral bkxxKPB) samples were taken Iron these recipients from six months to one year post transplant and analyzed by a Sequence Specific Priming (SSP) PCR assay that quanttatos the donor mismatched Class 11DNA from > 5% to 001% or one donor eel in ten thousand recipient cells. Ten Udmy-BMI wen analyzed win a level in their bone marrow of 0.84%(±0.14)ascomparedtottir PBo (0.26%(±OA). Whfcten controls (kidney transplant alone) did not demonstrate any chimerism hi both BMA and PB using this assay. These results demonstrate engraftment of donor ceHs in the BMA of BMI kidney recipients approximaWy 4 x that of their peripheral Mood. Whether this cMnerism represents an acceptance or lack of immune response to these cells by the recipient's Immune system is smi tobedMermined.
