Fetal microchimerism (FMc) describes long-term persistence of small numbers of fetal-derived allogeneic cells in the mother. Although FMc has been implicated as a mechanism of autoimmune disease, it may confer a beneficial effect with immune surveillance of malignant cells. We hypothesized that allogeneic FMc imparts a protective effect against breast cancer. Two observations provided a rationa...
WE HAVE PREVIOUSLY estimated a 20% frcquency of Epstein-Barr virus (EBV) related posttransplant lymphoproliferative disorders (PTLD) in small bowel allograft recipients. I The present study compares rates of PTLD among pediatric and adult recipients of isolated or composite small bowel allografts. We also report PTLD frequency before and after the institution of quantitative EBV monitoring and ...
The analysis of rare cells is not an easy task. This is especially true when cells representing a fetal microchimerism are to be utilized for the purpose of non-invasive prenatal diagnosis because it is both imperative and difficult to avoid contaminating the minority of fetal cells with maternal ones. Under these conditions, even highly specific biochemical markers are not perfectly reliable. ...
